Hello Guys
The query in this function returns the dependency for level one. However, I
need
the dependency for all level. I am still new with plpgsql so; how can I use
recursive function to return all dependency for all levels
CREATE OR REPLACE FUNCTION dependon (var text) RETURNS SETOF text AS
$BODY$
DECLARE
node record;
BEGIN
FOR node IN SELECT relname FROM pg_class WHERE OID in (
SELECT ev_class FROM pg_rewrite, pg_depend
WHERE pg_depend.objid = pg_rewrite.oid
AND deptype ='n'
AND refobjsubid = 1
AND refobjid::regclass::text = $1)
LOOP
IF node.relname IS NOT NULL THEN
RETURN NEXT depend(node.relname);
RETURN NEXT node.relname;
END IF;
END LOOP;
END
$BODY$
LANGUAGE 'plpgsql';
Regards

If you're using pgAdmin, there's a "Dependants" tab which shows you the objects
depending on another object.
Otherwise, I think you can query the pg_catalog.pg_depend table, but I don't
know how you go about that.
