Commit 5ee2197767 (about 4 years old) introduced the error: "IDENTIFY_SYSTEM has not been run before START_REPLICATION" But it seems like running START_REPLICATION first works (at least in the simple case). We should either: 1. Document that IDENTIFY_SYSTEM must always be run before START_REPLICATION, and always issue a WARNING if that's not done (an ERROR might break existing applications); or 2. If the commit is out of date and no longer needed, or if it's easy enough to fix, just remove the error (and Assert a valid ThisTimeLineID).
+1 to remove the error if START_REPLICATION can always work fine without IDENTIFY_SYSTEM. I found that the error happens when we connect to the standby and just run START_REPLICATION without IDENTIFY_SYSTEM. But I'm not sure if IDENTIFY_SYSTEM is actually necessary even in that case.
