[Pgpool-committers] pgpool - pgpool-II: Fix incorrect calculation of LSN in bytes.

[User T-ishii]

Log Message:
-----------
Fix incorrect calculation of LSN in bytes.

Change pg_last_xlog_receive_location() to
pg_last_xlog_replay_location() because the latter respects actually
replayed location which will give less chance for clients to have
stale data in standby.

Fix suggested by Anton Yuzhaninov.
