I believe savepoints are what you want: http://www.postgresql.org/docs/9.3/static/sql-savepoint.html Create a savepoint prior to each query, then decide how to proceed based on the success status of that query. For example, in the scenario you describe above: BEGIN SAVEPOINT q1 Q1 -> success RELEASE SAVEPOINT q1 SAVEPOINT q2 Q2 -> failure ROLLBACK TO SAVEPOINT q2 SAVEPOINT q3 Q3 -> success RELEASE SAVEPOINT q3 COMMIT In which case Q1 and Q3 would successfully be committed. -- Bill Moran -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
