Fix syntax error in native replication, when queries including now() etc. and "IN (SELECT ...)" in WHERE clause.

In native replication, queries including now() etc. are rewritten to a timestamp constant value.
However, Pgpool-II didn't support queries including now() etc. and "IN (SELECT ...)" in WHERE clause.

Per bug433.
