Commit Message

DB connection resilience behind the RDS Proxy (start: CONN_HEALTH_CHECKS) (#1536)

* Enable CONN_HEALTH_CHECKS for the database connections

With persistent connections (CONN_MAX_AGE > 0), an idle connection can be closed by the database server or a connection pooler/proxy in front of it. Reusing the now-dead connection surfaces as an occasional request error. CONN_HEALTH_CHECKS (Django 4.1+) verifies the connection is alive before reuse and transparently reopens it if not, removing the stale-reuse failures. Applies to both default and ro (ro copies default's config).

* Cap database connection setup with connect_timeout

Set connect_timeout=10 on the database connection. Without it a stalled connect blocks indefinitely, and the request hangs until the app server's worker timeout kills the worker (turning a connect hiccup into worker churn and a 5xx). Capping it makes a stalled connect fail fast and cleanly instead. 10s sits well above a normal sub-second connect, so a transient hiccup or a cold pooler/DB scale-up can still complete. Applies to both default and ro (ro copies default's config).
