Title: postgre "unrecognized configuration parameter 'sql_mode'" FIX

Severity: Warning --> pg_query() [function.pg-query]: Query failed: ERROR: unrecognized configuration parameter "sql_mode"
system/codeigniter/database/drivers/postgre/postgre_driver.php

Postgres does not have a sql_mode parameter... throws error when set.
