ALTER MATERIALIZED VIEW did not parse. After ALTER the parser expected an object keyword and stopped at MATERIALIZED, so a PostgreSQL schema that hands a materialized view to its owner, renames it or sets a storage parameter on it could not be read.

The statement reuses the AlterView node from #2730 with a materialized flag, since the two share their operations. OWNER TO, RENAME TO, RENAME COLUMN, SET SCHEMA, SET (...) and RESET (...) parse and round-trip through Display, and AS and ALTER COLUMN stay refused after MATERIALIZED.

PG 16 does accept ALTER MATERIALIZED VIEW m ALTER COLUMN c SET STATISTICS 100 / SET (n_distinct = 10) / SET STORAGE PLAIN; only SET/DROP DEFAULT is refused. This branch will have to be undone once AlterColumn grows those variants, so it may be simpler to drop it now and let AS/default-related forms fall through as they do for plain views.
