Previously, CREATEROLE users were permitted to make nearly arbitrary changes to roles that they didn't create, with certain exceptions, particularly superuser roles. Instead, allow CREATEROLE users to make such changes to roles for which they possess ADMIN OPTION, and to grant membership only in roles for which they possess ADMIN OPTION. When a CREATEROLE user who is not a superuser creates a role, grant ADMIN OPTION on the newly-created role to the creator, so that they can administer roles they create or for which they have been given privileges. With these changes, CREATEROLE users still have very significant powers that unprivileged users do not receive: they can alter, rename, drop, comment on, change the password for, and change security labels on roles. However, they can now do these things only for roles for which they possess appropriate privileges, rather than all non-superuser roles; moreover, they cannot grant a role such as pg_execute_server_program unless they themselves possess it. Patch by me, reviewed by Mark Dilger. Discussion: https://postgr.es/m/CA+TgmobN59ct+Emmz6ig1Nua2Q-_o=r6DSD98KfU53kctq_kQw@mail.gmail.com
