Urgh, I didn't meant it like that ;(
Sorry.

Anyway, maybe I didn't make myself clear enough.
Let's try again ;)

Let's say I have two functions in schema example
example.function1()
example.function2()
and two users
user1 and user2

Is there a way to grant user1 permission to execute function
example.function1(), but not example.function2()
And for user2 to be able to execute
example.function2() and not example.function1()?

To grant user1 permission to execute example.function1()
I need to do GRANT USAGE ON SCHEMA example to user1
But this permissions grants him also ability to execute example.function2()

GRANT EXECUTE ON FUNCTION example.function1() TO user1
or
REVOKE EXECUTE ON FUNCTION example.function1() FROM user1
don't have any affect.

Role PUBLIC don't have access to this schema so that is not an issue.
