Thread: pgsql: Make the standby server promptly handle interrupt signals.
Make the standby server promptly handle interrupt signals. This commit changes the startup process in the standby server so that it handles the interrupt signals after waiting for wal_retrieve_retry_interval on the latch and resetting it, before entering another wait on the latch. This change causes the standby server to promptly handle interrupt signals. Otherwise, previously, there was the case where the standby needs to wait extra five seconds to shutdown when the shutdown request arrived while the startup process was waiting for wal_retrieve_retry_interval on the latch.
