Question

I have two users Jason and postgres. Since I just started learning this, I have no idea why this code is not working. All I’m trying to do is drop an user, but am unable too. What’s wrong with my code?

postgres=# DROP OWNED BY Jason;
ERROR:  role "jason" does not exist
postgres=# \du
                             List of roles
 Role name |                   Attributes                   | Member of 
-----------+------------------------------------------------+-----------
 Jason     | Superuser, Create role, Create DB, Replication | {}
 postgres  | Superuser, Create role, Create DB, Replication | {}

Answer 1

Case sensitivity.

DROP OWNED BY "Jason";

PostgreSQL is case sensitive, it just lower-cases unquoted identifiers. To preserve case, “double quote” identifiers.
