survivesLostConnections() function

Keep a pool's lost idle connection from ending the process.

Signature:

export declare function survivesLostConnections<P extends Pool>(pool: P): P;

Parameters

Returns:

P

The same pool.

Remarks

When the server closes a connection the pool is holding idle — a pg_terminate_backend, a failover, a maintenance restart — pg emits error on the pool itself. With no listener, that is an unhandled error event and Node exits. The pool has already discarded the client by then and the next checkout opens a fresh one, so the only thing left to do is say so.
