Got a postgreSQL database and model class class Pro_Model_Name extends Zend_Db_Table_Abstract { protected $_name = 'TableName'; // protected $_primary = 'TableName_ID'; protected $_sequence = 'tablename_id_seq'; ... }

There's an insertion $insert = array( 'TableName_ID'=>$id, 'TableNameType_ID'=>$c, 'Value'=>$v ); $this->insert($insert); It began to fail in 1.11.0 or maybe even earlier.

Fixed this way: 1) Sequence renamed to CamelCase: TableName_id_seq 2) Model prpoperty renamed to protected $_sequence = 'TableName_id_seq';
