Subject: Correctly initialise shared recoveryLastRecPtr in recovery.
X-Git-Tag: REL9_1_3~10

Correctly initialise shared recoveryLastRecPtr in recovery.
Previously we used ReadRecPtr rather than EndRecPtr, which was
not a serious error but caused pg_stat_replication to report
incorrect replay_location until at least one WAL record is replayed.
