External database requirements

If you plan to run CD against an external database, the instance must meet:

  • PostgreSQL 17 — Amazon RDS for PostgreSQL, Amazon Aurora (PostgreSQL-compatible), or a self-managed PostgreSQL server.

  • Reachable from the CD host on its TCP port (default 5432).

  • TLS enabled, with a server certificate valid for the configured hostname and chaining to a CA you can supply as a PEM file. CD always connects with sslmode=verify-full.

  • max_connections of at least ~60 (10 for the backend, 50 for the query service, plus headroom). On RDS or Aurora, a db.t3.small or larger is sufficient.

  • The pgcrypto and lo extensions must be permitted if your instance restricts extensions.

The cd4pe and query databases must be on the same instance.
