Re: Obfuscated stored procedures (was Re: [GENERAL] Oracle and Postgresql)

Added to TODO under features not wanted:

Incomplete itemObfuscated function source code (not wanted)

Obfuscating function source code has minimal protective benefits
because anyone with super-user access can find a way to view the code.
To prevent non-super-users from viewing function source code, remove
SELECT permission on pg_proc.

I understand in reality it provides no real extra security but somehow users being able to easily view something they don't have access to execute beyond it's name just feels wrong.
