Except for GRANT and REVOKE on roles, the GRANTED BY clause currently only accepts the current role to match the SQL standard. And even if an acceptable grantor (i.e., the current role) is specified, Postgres ignores it and chooses the "best" grantor for the command. Allowing the user to select a specific grantor would allow better control over the precise behavior of GRANT/REVOKE statements. This commit adds that ability. For consistency with select_best_grantor(), we only permit choosing grantor roles for which the current role inherits privileges.
