+ ResetLatch(&MyProc->procLatch); + rc = WaitLatchOrSocket(&MyProc->procLatch, + WL_POSTMASTER_DEATH | WL_SOCKET_READABLE | + WL_LATCH_SET, + PQsocket(streamConn), + 0, + WAIT_EVENT_LIBPQWALRECEIVER_READ); + if (rc & WL_POSTMASTER_DEATH) + exit(1); Hmm. We have always been very careful about not leaving immediately from libpqwalreceiver.c which is an independent shared library so as the WAL receiver can take cleanup actions.
