It would seem logical to use the same logic for archive recovery as we
do for streaming replication, and only set XLogReceiptTime when you have
to wait for a WAL segment to arrive into the archive, ie. when
restore_command fails.
That would not do what you want at all in the case where you're
recovering from archive --- XLogReceiptTime would never advance
at all for the duration of the recovery.
Do you mean when using something like pg_standby, which does the waiting
itself?
It might be useful if you knew that it was a standby-with-log-shipping
situation, but we have no way to tell the difference.
With pg_standby etc. you use standby_mode=off. Same with traditional
archive recovery. In standby mode, it's on.
