How to pass 'User Password' as parameter in function?

Question

I'm trying to create users with a Function in Postgres. PostGres does not allow me to set a user's password with a parameter.

I've tried casting the parameter to all kinds of different types. Quoting literal on it. Nothing works.

Code:

CREATE OR REPLACE FUNCTION
    userlogic_add_user(user_password text)

    ALTER USER user_name WITH user_password;

The error msg I receive is Syntax related. But it has something to do with user_password.

The entire code obviously looks a bit different, but these are the parts of interest.

I guess you can always try executing a dynamic command :

EXECUTE ('ALTER USER ' || quote_ident(user_name) || ' WITH PASSWORD ' || quote_ident(user_password) || ';')
