I'd like to delete all the image files from a table by issuing an interactive psql command. Given CREATE TABLE image ( name text, rast oid ); with most tuples having images in rast, wanna do something like => select lo_unlink('select rast from image'); Can such a thing be done, and how? I guess I've forgotten the syntax. Or will an update that sets the oids to null or 0 work? (pgsql 9.1.2) Thanks. - Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
