# Co-op Cloud entrypoint wrapper for the discourse/postgres image.
#
# The image (https://github.com/discourse/discourse-postgres) handles everything
# itself, including the in-place major-version pg_upgrade on boot. The only thing
# it can't do for us is read the docker secret: it expects the DB password in the
# DB_PASSWORD / POSTGRES_PASSWORD env vars (no *_FILE support), so inject it from
# /run/secrets here, then hand off to the image's real entrypoint.
#
# The install user and data-checksum settings the upgrade needs are passed as
# plain env vars in compose.yml (POSTGRES_USER, POSTGRES_INITDB_ARGS).
