# Trigpoint release build. Two stages:
#   build   — pgvector's image plus the server headers and a compiler; builds the extension (release variant: no page
#             hooks, no result-changing diagnostics; TEST_HOOKS=1 for the test image) and packs it as
#             postgresql-${PG_MAJOR}-trigpoint_${VERSION}_${ARCH}.deb (dpkg-deb; depends on postgresql-${PG_MAJOR}; pgvector >= 0.8
#             is a Recommends, since pgvector's image compiles it from source and has no package for it)
#   release — pgvector/pgvector:pg${PG_MAJOR} plus that .deb: no compiler, no other extensions
#
#   docker build -f docker/Dockerfile.release --build-arg PG_MAJOR=17 -t trigpoint/postgres:0.5-pg17 .
#   docker build -f docker/Dockerfile.release --build-arg PG_MAJOR=17 --target deb -o dist .     # the .deb alone
#   docker build -f docker/Dockerfile.release --build-arg TEST_HOOKS=1 -t trigpoint-postgres-test:pg17 .   # for the suites
#   --build-arg ARCHFLAGS=-march=x86-64-v3   # a package for other x86-64 machines (default: -march=native)

# The base images are pinned by digest: the tag pgvector/pgvector:pg<m> is rebuilt upstream, and two builds of the same
# tree on different digests gave different indexes (most likely through the toolchain).
# These are the digests 0.5 was tested on (2026-11-04). To move: update all three, then rerun the matrix and no-drift.
