Hello! I have the following question.<br /><br />For example I have a role ID1 with members ID2 and ID3.<br />Role ID2
hasalso members ID4 and ID5. It means that roles ID4 and ID5 are members of ID1.<br />The question: Is there any
functionin PostgreSQL, that finds all the members of role ID1 - even such members, as ID4 and ID5. <br /><br />Thanks.
