# Builds the database images of debug/ and pushes each to Docker Hub as a
# tag of testflows/machine-examples, by name and version:
#
#   :clickhouse-server-26.8.31.2   :clickhouse-debug-26.8.31.2
#   :postgresql-server-17.11       :postgresql-debug-17.11
#
# and the same with -YYYYMMDD-HHMM, so a rebuild of one version keeps the
# builds before it. The version is the server's, from its Dockerfile's FROM
# line: a new server release is a new tag beside the old ones. Run by hand: a
# new image is a release.
