Switch to LIFO for the connection pool
Using a FIFO for the connection pool can lead to issues when there are upstream components (pgbouncer, haproxy, etc.) that terminate connections that are idle after a period of time. Switching to a LIFO reduces the probability that a thread will checkout a connection that is about to be closed by an idle timeout in an upstream component.
