# Postgres 15 override for self-hosted Supabase.
#
# Postgres 17 is now the default in docker-compose.yml. Use this override to pin
# Postgres 15, for two cases:
#   1. An existing Postgres 15 deployment that has not been upgraded yet.
#   2. As the rollback target for utils/upgrade-pg17.sh (PG 15 and PG 17 use
#      different postgres UIDs, so rollback must start with the PG 15 image).
#
# Usage:
#   docker compose -f docker-compose.yml -f docker-compose.pg15.yml up -d
#
# To upgrade an existing Postgres 15 database to Postgres 17 in place, see:
# - https://supabase.com/docs/guides/self-hosting/postgres-upgrade-17
# - utils/upgrade-pg17.sh
