That seems inconsistent. If querying through a view doesn't adopt the BYPASSRLS right (or lack thereof) of the view owner, and I agree that it shouldn't, then it also shouldn't disregard the fact that the person issuing the query has that right. In other words, we've made a decision, when going through views, to test ACLs based on who owns the view. We do that in all cases, not only sometimes. Now, when querying a view, whose BYPASSRLS privilege do we consult? It should either be the person issuing the query in all cases, or the view owner in all cases, not some hybrid of the two. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
