[SQL] Log, Logs and more Logs

Hi list, I lost some data becouse my application does not throws an exception when an update statement report an error. It is possible to find out if the PostgreSQL could have this error (and more important the complete statement that make this errors occurs) ? I know there are many logs in pos
