[pgpool-committers: 4410] pgpool: Fix timestamp data inconsistency by replication mode.

[Bo Peng]

Fix timestamp data inconsistency by replication mode.

From PostgreSQL10 the column default value such as 'CURRENT_DATE' changes,
Pgpool-II should also rewrite timestamp by the added default values in stead of
"'now'::text::date".
