Adjust comment about timeout when waiting for WAL at recovery
A timeout of 5s is used when waiting for WAL to become available atrecovery so as the startup process is able to react promptly if atrigger file shows up. However this missed the fact that the startupprocess also relies on the timeout to check periodically the status ofany active WAL receiver.Discussion:https://postgr.es/m/20190131070956.GE13429@paquier.xyz
