Hello Tom, Thanks - I get "pg_db_role_setting" as a response. I have already attempted to reindex system but get: NOTICE: table "pg_catalog.pg_class" was reindexed NOTICE: table "pg_catalog.pg_statistic" was reindexed NOTICE: table "pg_catalog.pg_type" was reindexed NOTICE: table "pg_catalog.pg_attribute" was reindexed NOTICE: table "pg_catalog.pg_authid" was reindexed ERROR: could not open file "base/11919/11680": No such file or directory John > -----Original Message----- > From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] > Sent: Mittwoch, 4.
