Is there a sample somewhere how this could be done? I'm runnig PG 8.4 on a windows machine. Perhaps when you delete your record, you can use a before delete trigger to insert this path to a "Files_To_Delete" table. Then using Cron, you can query this table to get the list of file you want to delete. On the other hand, if you really want to delete each file with a trigger, you are probably better off using Large Objects (lo): http://www.postgresql.org/docs/8.4/interactive/lo.html And in the off chance that you one day use the truncate command you can periodically schedule the vacuumlo command: http://www.postgresql.org/docs/8.4/interactive/vacuumlo.html -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
