* let limit and offset use bind parameter * format * format limt_test * try again * fix test case fro connpool * adding driverName for postgres ,if not to do so, the stmt vars will be added a wrong one called pgx.QueryExecModeSimpleProtocol , causing the SQL with limit problem need 1 parameter ,but given two. * delete trunk files * restore the test_test.go * restore test_test.go * driver/postgres->v1.5.5 * change postgres version rollback to 1.5.4 --------- Co-authored-by: chenchuan <chenchuan@360.cn> Co-authored-by: jason_chuan <jason_chuan@126.com>
