Pool sizing for withPostgresClient and withPostgresAdminClient. Two entries on the same connection string share a pool only when their options resolve to the same values.
Connections this process opens at most on this connection string. A positive integer. The pooler team recommends one to four for serverless deployments.
Milliseconds a query waits for a free connection before failing with `POSTGRES_POOL_BUSY`, and how long a new connection may take to come up. A positive number. Keep it well under the pooler's own 60 second checkout timeout so the failure surfaces here, with a message that says what happened.
