        updated server to run table-drop and session-end queries after the
                session-end commit/rollback, as some queries on some platforms (

        fixed bugs in the mysql and postgresql connection code that assumed
                that the bind variables were bound in order, independent of

        resolved a paradox involved in detecting whether the current mysql
