DATABASE_URL=postgres://postgres:postgres@127.0.0.1:5432/postgres

# Cloud SQL Auth Proxy (Unix socket) — set these instead of DATABASE_URL on Cloud Run.
# When using a Unix socket, authentication is handled by IAM; DB_PASSWORD is not required.
# INSTANCE_UNIX_SOCKET=/cloudsql/PROJECT:REGION:INSTANCE
# DB_PASSWORD=****
# DB_USER=postgres # IAM service-account name (mapped to a PG user) or a built-in PG user
# DB_NAME=postgres
# DB_USE_UNIX_SOCKET=true # set to "false" to force DATABASE_URL even when INSTANCE_UNIX_SOCKET is set

# `openssl rand -hex 32`
