## Security considerations
* Non-RDS `change_valid_until` function does not uses `ALTER USER` to modify `VALID UNTIL`, it makes an `update pg_catalog.pg_authid set rolvaliduntil` instead, so the `dba` user has only grant over that table/column instead of granting additional permissions to him.
* RDS `change_valid_until` should run as the database owner, is the only way to make this work as you can't access `pg_catalog.pg_authid` on rds, it uses `ALTER USER ... VALID UNTIL` instead.
