Report WAL flush, not insert, position in replication IDENTIFY_SYSTEM
When beginning streaming replication, the client usually issues theIDENTIFY_SYSTEM command, which used to return the current WAL insertposition. That's not suitable for the intended purpose of that field,however. pg_receivexlog uses it to start replication from the reportedpoint, but if it hasn't been flushed to disk yet, it will fail. ChangeIDENTIFY_SYSTEM to report the flush position instead.Backpatch to 9.1 and above. 9.0 doesn't report any WAL position.
