name: Base image

# Builds and pushes the pgaf-base image to ghcr.io.
#
# The base image contains every supported Postgres major version
# (from apt.postgresql.org) plus one Citus build per Postgres version.
# Per-PG pg_auto_failover builds use it as their FROM so the heavy
# apt/Citus work is cached long-term across all PR runs.
#
# Triggered by:
#   - push:  changes to Dockerfile.base on main
#   - workflow_dispatch:  manual rebuild (optionally force)
#   - workflow_call:  called by run-pgaftest.yml on cache-miss
#   - check-versions.yml:  when PGDG or Citus versions change
