Fix incorrect time stamp rewriting in replication mode for certain time zones.

Time stamp rewriting calls "SELECT now()" to get current
time. Unfortunately the buffer for the current time is too small for
certain time zones such as "02:30". Note that non-30-minutes-time-zone
such as "0900" does not reveal the problem. This explains why we
haven't the bug report until today. Bug reported in [pgpool-general:
2113] and fix provided by Sean Hogan.
