From 99cd2f8ce3f9f936084a209c9f1d41f1b8be67bc Mon Sep 17 00:00:00 2001 From: Javier de la Torre Date: Fri, 20 Mar 2026 05:40:02 +0100 Subject: [PATCH 001/116] feat: propagate GEOMETRY CRS through PostGIS in both directions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DuckDB 1.5 introduced CRS metadata on the GEOMETRY type (e.g., GEOMETRY('EPSG:4326')). This change makes that CRS survive a full round trip through PostgreSQL/PostGIS via postgres_scanner. Write side (DuckDB → PostGIS): - WriteGeometry detects CRS on the LogicalType and writes EWKB instead of plain WKB so PostGIS receives the SRID: WKB: [byte_order:1] [type:4] [payload...] EWKB: [byte_order:1] [type|0x20000000:4] [srid:4] [payload...] Falls back to plain WKB when no CRS is set, preserving the previous behavior. (Uses GeoType::HasCRS / GeoType::GetCRS — the earlier draft mistakenly referenced LogicalType::GetCRS, which does not exist on DuckDB 1.5.) Read side (PostGIS → DuckDB): - TypeToLogicalType decodes the SRID from PostGIS's column-level typmod for `geometry(TYPE, SRID)` columns and returns LogicalType::GEOMETRY("EPSG:N") instead of plain GEOMETRY(). The typmod layout is: bits 0 : has-M bits 1 : has-Z bits 2-7 : geometry type code (POINT=1, LINESTRING=2, ...) bits 8-29 : SRID Untyped `geometry` columns carry typmod -1 and fall back to plain GEOMETRY (no CRS), matching the previous behavior. Before: DuckDB GEOMETRY('EPSG:4326') → PostGIS geometry(SRID=0) PostGIS geometry(POINT,4326) → DuckDB GEOMETRY (no CRS) After: DuckDB GEOMETRY('EPSG:4326') → PostGIS geometry(SRID=4326) PostGIS geometry(POINT,4326) → DuckDB GEOMETRY('EPSG:4326') Co-Authored-By: Claude Opus 4.7 (1M context) --- src/include/postgres_binary_writer.hpp | 41 +++++++++++++++++++++++++- src/postgres_utils.cpp | 14 +++++++++ 2 files changed, 54 insertions(+), 1 deletion(-) diff --git a/src/include/postgres_binary_writer.hpp b/src/include/postgres_binary_writer.hpp index fef2fafe0..6f423930a 100644 --- a/src/include/postgres_binary_writer.hpp +++ b/src/include/postgres_binary_writer.hpp @@ -10,6 +10,7 @@ #include "duckdb.hpp" #include "duckdb/common/types/interval.hpp" +#include "duckdb/common/types/geometry_crs.hpp" #include "duckdb/common/serializer/memory_stream.hpp" #include "postgres_conversion.hpp" @@ -207,6 +208,44 @@ class PostgresBinaryWriter { stream.WriteData(const_data_ptr_cast(str_data), str_size); } + //!

Two strip points in this file: 1. ToPostgresType (called by AddCastToPostgresTypes during CTAS planning) returned LogicalType::GEOMETRY() unconditionally, dropping CRS before the projection that feeds the new physical plan. Now returns the input unchanged for GEOMETRY so CRS survives the cast/projection. 2. TypeToString returned plain "GEOMETRY" for any GEOMETRY type and would have been short-circuited anyway by the HasAlias() early return (GEOMETRY('EPSG:N') carries an alias of "GEOMETRY"). The new branch runs *before* HasAlias, detects CRS via GeoType::HasCRS, and emits `geometry(Geometry, N)` so PostGIS records the SRID in pg_attribute.atttypmod and the existing read-side typmod decode picks it up. Verified end-to-end through the streamability harness in duckdb-warehouse-transfer: postgres -> oracle and postgres -> snowflake now round-trip GEOMETRY('EPSG:3857') with byte-perfect WKB and CRS preserved at the destination, with no plan-level materialization.

DuckDB rewrites a CONNECT passthrough statement into postgres_query() (PostgresCatalog::RemoteExecute). Its bind, PGQueryBind, never called PostgresScanFunction::PrepareBind - which is where every server capability decision is made, including the Redshift opt-out from the binary COPY protocol. As a result the CONNECT path always wrapped the query in COPY (...) TO STDOUT (FORMAT "binary"), which Redshift does not support. Instead of duplicating the Redshift check on each bind path, make the protocol a property of the attached database: - add a use_text_protocol ATTACH option, accepting TRUE / FALSE / 'auto' (the default), stored on the PostgresCatalog - PostgresCatalog::UseTextProtocol() is now the single place resolving the protocol for a database: an explicit option wins, 'auto' falls back to the pg_use_text_protocol setting or to Redshift auto-detection - PGQueryBind calls PrepareBind, so the CONNECT path resolves it as well Also resolve the protocol at the start of PrepareBind: it was set after the ctid scan and max_threads decisions that depend on it, which happened to be harmless only because Redshift reports major version 8. --- src/include/postgres_version.hpp | 4 + src/include/storage/postgres_catalog.hpp | 20 +++- src/postgres_query.cpp | 4 +- src/postgres_scanner.cpp | 15 ++- src/postgres_storage.cpp | 26 ++++- src/storage/postgres_catalog.cpp | 5 +- test/sql/storage/attach_text_protocol.test | 110 +++++++++++++++++++++ 7 files changed, 174 insertions(+), 10 deletions(-) create mode 100644 test/sql/storage/attach_text_protocol.test diff --git a/src/include/postgres_version.hpp b/src/include/postgres_version.hpp index d26b0526a..aa1db5090 100644 --- a/src/include/postgres_version.hpp +++ b/src/include/postgres_version.hpp @@ -14,6 +14,10 @@ namespace duckdb { enum class PostgresInstanceType { UNKNOWN, POSTGRES, AURORA, REDSHIFT }; +//!

FROM STDIN (FORMAT BINARY)` when performing inserts into Postgres tables. This can cause problems with some Postgres-wire-compatible databases that do not support `COPY`. This PR adds support for performing plain batch `INSERTs` instead of the `COPY`. Existing option `pg_use_text_protocol` is used to enable this behaviour. Currently only basic column types are supported, support for composite types (`ARRAY`, `LIST`, `STRUCT`) may be added in future. Testing: existing type tests are updated to also run with text protocol enabled. --- src/include/storage/postgres_insert.hpp | 48 +++- src/storage/postgres_insert.cpp | 244 +++++++++++++++++-- test/sql/storage/attach_types_blob.test | 10 + test/sql/storage/attach_types_char.test | 16 ++ test/sql/storage/attach_types_date.test | 12 + test/sql/storage/attach_types_decimal.test | 10 + test/sql/storage/attach_types_enum.test | 20 ++ test/sql/storage/attach_types_interval.test | 10 + test/sql/storage/attach_types_json.test | 10 + test/sql/storage/attach_types_macaddr.test | 10 + test/sql/storage/attach_types_time.test | 10 + test/sql/storage/attach_types_timestamp.test | 18 ++ test/sql/storage/attach_types_uuid.test | 10 + test/sql/storage/attach_types_varchar.test | 10 + 14 files changed, 412 insertions(+), 26 deletions(-) diff --git a/src/include/storage/postgres_insert.hpp b/src/include/storage/postgres_insert.hpp index d4ea3d24e..072006390 100644 --- a/src/include/storage/postgres_insert.hpp +++ b/src/include/storage/postgres_insert.hpp @@ -15,17 +15,18 @@ #include "duckdb/planner/parsed_data/bound_create_table_info.hpp" #include "duckdb/planner/logical_operator.hpp" #include "duckdb/common/index_vector.hpp" +#include "storage/postgres_catalog.hpp" namespace duckdb { class PostgresInsert : public PhysicalOperator { public: //!

Skip the header while scanning for row boundaries on the first fill, but keep it in the buffer so CheckHeader can still validate it.

PQgetCopyData allocates even when it hands back a length we cannot use, and buffer was only assigned after the check, so FreeBuffer() never saw it. Assign it first and let the existing ownership do the freeing. The three COPY error paths passed a possibly null PGresult to PQresultErrorMessage(). libpq returns an empty string rather than crashing, which is how "Failed to copy data: " with no reason after it gets produced. A null result means the connection failed, so report PQerrorMessage() in that case - the same pattern ExecuteQueries() and PostgresQueryBind() already use.

Subject: [PATCH 056/116] Allow non-preparable queries in postgres_query After #552 the `postgres_query()` function is also used to run DDL and DML queries. Though the queries are still being prepared on a remote server before execution (this is necessary to get the resulting columns during binding) - the same "general" code path is used for both `SELECT`s and DML queries. For majority of the queries this does not cause problems, as Postgres (comparing to other DBs) has minimal limitations to queries that cannot be prepared. Though two notable groups that cannot be prepared contain utility queries (like `VACUUM`) and concatenated multi-query strings. This PR adds support for a `prepare=FALSE` named parameter to `postgres_query()` that makes such calls to use the "fast-path", when the input string is run in Postgres at once without preparing it. This non-prepared mode does not allow to specify query parameters and does not return a result set - intended to be used only with utility or DML queries. Testing: existing `postgres_query` test is updated with multi-query strings coverage. --- src/postgres_query.cpp | 64 +++++++++++++++++----------- test/sql/scanner/postgres_query.test | 50 ++++++++++++++++++++++ 2 files changed, 90 insertions(+), 24 deletions(-) diff --git a/src/postgres_query.cpp b/src/postgres_query.cpp index 7069be166..77a2cfac6 100644 --- a/src/postgres_query.cpp +++ b/src/postgres_query.cpp @@ -22,10 +22,37 @@ static bool ExtractFlag(TableFunctionBindInput &input, const string &name, bool return default_val; } -static unique_ptr PGQueryBind(ClientContext &context, TableFunctionBindInput &input, - vector &return_types, vector &names) { +static unique_ptr BindDML(ClientContext &context, TableFunctionBindInput &input, + vector &return_types, vector &names, + PostgresCatalog &pg_catalog, PostgresConnection &con, std::string sql, + bool use_transaction) { + // The statement returns no result columns: it's a command (DDL, or DML without RETURNING). + // Instead of failing, run it as a command and return a single-row Success result.

These asserts are skipped in production builds and providing a schema that doesn't match the data resulted in incorrect data instead of an error. CONTRIBUTING.md says user input checks should not be done with D_ASSERT, so convert them into exceptions. Now a hard error is raised instead of ignoring the mismatch and misparsing the data. Since COPY format carries length but not types, this can not detect all mismatches. Types of equal length like bigint and double can be misinterpreted, so it is still the responsibility of the user to make sure the types match. This same parser decodes COPY output while loading from a postgres query, where a schema change between the catalog read and the COPY can produce mismatches (#594). This does not fix that race, but at least will turn it into an error in more, but not all, cases. Renamed the local variable tuple_count to field_count to match what the COPY format calls it. tuple_count implied it was the number of rows instead of the number of columns. --- src/postgres_binary_parser.cpp | 55 ++++++++++------ .../postgres_binary_read_schema_mismatch.test | 62 +++++++++++++++++++ 2 files changed, 98 insertions(+), 19 deletions(-) create mode 100644 test/sql/misc/postgres_binary_read_schema_mismatch.test diff --git a/src/postgres_binary_parser.cpp b/src/postgres_binary_parser.cpp index 63fd24832..70733c53b 100644 --- a/src/postgres_binary_parser.cpp +++ b/src/postgres_binary_parser.cpp @@ -23,16 +23,19 @@ bool PostgresBinaryParser::ReadChunk(DataChunk &output, const vector & return false; } - auto tuple_count = ReadInteger(); - if (tuple_count <= 0) { - // tuple_count of -1 signifies the file trailer (i.e. footer) + auto field_count = ReadInteger(); + if (field_count <= 0) { + // a field count of -1 signifies the file trailer (i.e. footer) // clear the buffer so Ready() returns false and the caller can free it buffer_ptr = nullptr; end = nullptr; continue; } - D_ASSERT(tuple_count == column_ids.size()); + if (field_count != column_ids.size()) { + throw InvalidInputException("Postgres binary reader - expected %llu field(s) per row, got %d", + column_ids.size(), field_count); + } idx_t output_offset = output.size(); for (idx_t output_idx = 0; output_idx < output.ColumnCount(); output_idx++) { @@ -153,6 +156,16 @@ void PostgresBinaryParser::ReadArray(const LogicalType &type, const PostgresType ListVector::SetListSize(out_vec, child_offset + child_count); } +// Check that the length of the value Postgres sent matches the length we expect.

That used to be cheap: DataChunk::SetCardinality only stored the count. Since DuckDB 2.0 vectors carry their own size, and the update to it (573bcfd) replaced the call with DataChunk::SetChildCardinality, which visits every vector of the chunk (and, through VectorBuffer::SetVectorSize, the children of struct and array vectors). A 2048-row chunk now paid for that 2048 times. The parser goes back to storing only the count per row, with SetCardinalityUnsafe (what the deprecated SetCardinality does), and the readers sync the vector sizes with SetChildCardinality once, before handing the chunk back. It can't happen at the end of the parser's loop: libpq hands over COPY data one row per PQgetCopyData call, so that would still be once per row. Nothing reads a vector's size while a chunk is being filled: values are written by row offset, bounded by the vector's capacity, and list child sizes are tracked separately by ListVector. Single-threaded user-mode cycles, median of 9 interleaved runs: table scan of one int column (10M rows) -14%, five columns -4%, a 12-type table (3M rows) -12%, postgres_query -13 to -14%, read_postgres_binary -18 to -25%.

From: Alex Kasko Date: Tue, 13 Oct 2026 22:52:00 +0100 Subject: [PATCH 102/116] Allow running postgres_query on a specific conn This PR adds 2 new scalar functions: - `postgres_pin_connection`(``: `VARCHAR`) -> `UBIGINT` - `postgres_close_pinned_connection`(``: `VARCHAR`, ``: `UBIGINT`) -> BOOL `postgres_pin_connection` acquires a connection from the connection pool of the specified attached database and "pins" that connection returning its ID as a handle. This handle can be specified to the `postgres_query()` function to make it run on that specific connection. This allows to make multiple subsequent `postgres_query()` and `postgres_execute()` calls on the same connection, thus keeping consistent server session state. Pinned connection remains "active" and takes a slot in the connection pool until it is closed by calling `postgres_close_pinned_connection`. Usage example: ```sql ATTACH '...' AS s (TYPE postgres); SET VARIABLE conn = postgres_pin_connection('s'); CALL postgres_execute('s', 'CREATE TEMPORARY TABLE temp1(col1 INT)', connection=getvariable('conn')); CALL postgres_execute('s', 'INSERT INTO temp1 values(42)', connection=getvariable('conn')); FROM postgres_query('s', 'SELECT * FROM temp1', connection=getvariable('conn')); ---- 00:42:00 SELECT postgres_close_pinned_connection('s', getvariable('conn')); ``` Testing: `query_pin_connection.test` added. --- src/CMakeLists.txt | 1 + src/include/postgres_scanner.hpp | 12 +++ src/include/postgres_utils.hpp | 2 + src/postgres_extension.cpp | 6 ++ src/postgres_pin_connection.cpp | 64 ++++++++++++ src/postgres_query.cpp | 113 ++++++++++++++------- src/postgres_scanner.cpp | 62 +++++++++-- src/postgres_utils.cpp | 14 +++ test/sql/scanner/query_pin_connection.test | 96 +++++++++++++++++ 9 files changed, 325 insertions(+), 45 deletions(-) create mode 100644 src/postgres_pin_connection.cpp create mode 100644 test/sql/scanner/query_pin_connection.test diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index 0bc407844..f8138d09d 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -17,6 +17,7 @@ add_library( postgres_filter_pushdown.cpp postgres_hstore.cpp postgres_parameters.cpp + postgres_pin_connection.cpp postgres_query.cpp postgres_scanner.cpp postgres_secrets.cpp diff --git a/src/include/postgres_scanner.hpp b/src/include/postgres_scanner.hpp index c992c319d..46a4b2803 100644 --- a/src/include/postgres_scanner.hpp +++ b/src/include/postgres_scanner.hpp @@ -65,6 +65,8 @@ struct PostgresBindData : public FunctionData { string limit_clause;
