Users reported messages similar to "could not open file "global/11801": No such file or directory" I'd try "select relname from pg_class where pg_relation_filenode(oid) = 11801" to see if you can identify the problematic relation that way. If you're lucky, this is just loss of some system catalog index in which case reindexing will fix it. The fact that you're able to get through connecting, and the errors only show up with queries, is somewhat promising given that the problem looks like it's related to pg_authid or pg_db_role_setting. regards, tom lane
