Hi, At the first time: I'm in newbie in SQL... I'm sorry!
My question is: How can I get the usernames of a group (for example 'osztatlan_users') from SQL? I try it: SELECT usename FROM pg_user WHERE usesysid IN (SELECT grolist FROM pg_group WHERE groname='osztatlan_users') ORDER BY pg_user; But I get the next error message: ERROR: operator does not exist: oid = oid[] HINT: No operator matches the given name and argument type(s). You may need to add explicit type casts. I see, what is the problem, but what can I do...?
