Fix pg_recvlogical avoidance of superfluous Standby Status Update.
The defect suppressed a Standby Status Update message when bytes flushed
to disk had changed but bytes received had not changed. If
pg_recvlogical then exited with no intervening Standby Status Update,
the next pg_recvlogical repeated already-flushed records. The defect
could also cause superfluous messages, which are functionally harmless.
Back-patch to 9.5 (all supported versions).
