By default, they can't. Perhaps you granted create permission on the
database to PUBLIC? Also, are you sure the users in question are
not superusers?

There doesn't seem to be a psql backslash command that shows permissions
on databases; you'd need to look directly at pg_database, eg
select datname, datacl from pg_database;
