Hello,
pg_get_functiondef() can be used quite easily by using a cast to regprocedure,
like this:
select pg_get_functiondef('public.foo(text, text, text)'::regprocedure);
However if the function is defined with an out parameter like this:
create or replace function foo(p1 text, p2 out text, p3 text)
....
the above cast does not work. Postgres returns an error: "function
public.foo(text,text,text) does not exist.
'public.foo(text, OUT text, text)'::regprocedure does not work either.
So, what should be the right format to write the string literal that can be
cast to the correct regprocedure?
Thanks
Thomas
