[pgpool-committers: 499] pgpool: Fix send_to_where() when SET TRANSACTION ISOLATION LEVEL SERIAL

[Tatsuo Ishii]

Fix send_to_where() when SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
case in streaming replication mode. It is sent to not only primary but
also to standby and of course this causes an error.
Similar SQLs are:
 SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL SERIALIZABLE or
 SET transaction_isolation TO 'serializable'
 SET default_transaction_isolation TO 'serializable'

Original complain is [pgpool-general: 715].
