Re: How can I display the contents of a function?

Another reason to look forward to 8.4. :)

Does that function return information in an identical way to selecting from pg_proc?

Just for info:

wait for the upcoming new release 8.4, it contains a function called
pg_get_functiondef(). Example:

test=# create or replace function foo(in a int) returns int as $$begin return a*10; end; $$language plpgsql;
CREATE FUNCTION
test=# select pg_get_functiondef('foo'::regproc);
               pg_get_functiondef
--------------------------------------------------
 CREATE OR REPLACE FUNCTION public.foo(a integer)
 RETURNS integer
 LANGUAGE plpgsql
 AS $function$begin return a*10; end; $function$

(1 row)
