Hi, I created a function called "isnull" for test
purposes and when trying to replace it returns the
message belows :
-- Function: public.isnull(anyelement)
-- DROP FUNCTION public.isnull(anyelement);
CREATE OR REPLACE FUNCTION public.isnull(anyelement)
RETURNS bool AS
'
SELECT $1 is null;
'
LANGUAGE 'sql' VOLATILE;
ERROR: syntax error at or near "isnull" at character
120
Thanks.
