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.
