Default max=20 was saturating during normal admin clickthrough — the
clients list page does aggregate-per-client queries (yachts, memberships,
interests, contacts) that fan out 5-6 connections per row, plus
dashboard analytics, plus React Query refetch-on-focus. With 20 slots,
the server appeared to hang for 30s (statement_timeout) until queries
released their slots. Production keeps the conservative max=20 since
multi-replica deployments share the postgres max_connections budget.
