# PostGIS + pgvector.
#
# postgis/postgis images for PG16 are bullseye-based and their Debian release
# files have expired (EOL), so a plain apt update fails. Two fixes baked in:
#   - Acquire::Check-Valid-Until=false  (the repos are still served)
#   - the pgdg signing key (trusted.gpg.d accepts ASCII-armored keys)
# then postgresql-16-pgvector from pgdg gives us the `vector` extension.
