# Isolated PostgreSQL for NestJS integration tests.
# - Port 5433 (not 5432) so it never conflicts with your local dev Postgres.
# - tmpfs mount: the entire DB lives in RAM. Zero residual data after `docker compose down`.
# - Never pointed at Neon — this is test-only infrastructure.
#
# Usage:
#   docker compose -f docker-compose.test.yml up -d    # start before tests
#   docker compose -f docker-compose.test.yml down      # stop + wipe after tests
