That's pretty bizarre, but what makes you think it has anything to do with temp tables? OID 2678 is pg_index_indexrelid_index itself. It looks to me like you must have duplicate rows in pg_index for that index (and maybe others?), and the problem is exposed during vacuum full because it tries to rebuild the indexes. Could we see the output of select ctid,xmin,xmax,* from pg_index where indexrelid in (select indexrelid from pg_index group by 1 having count(*)>1); regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
