What problem are you trying to solve? PostgreSQL 8.0 introduced savepoints, which you can use in PL/pgSQL via an EXCEPTION clause: http://www.postgresql.org/docs/8.0/interactive/plpgsql-control-structures.html#PLPGSQL-ERROR-TRAPPING Another possibility might be to use dblink to make another connection to the database from within the function and execute transactions over that connection. -- Michael Fuhr ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
