We have been known to emphasize that unless you have an ORDER BY clause at the outermost level of a query, there is no guarantee about the order of rows returned. In general, even with autovacuum off and no DML running, the same query can return rows in a different order because of synchronized scans -- so I would tend to view the lack of complaints as a sign of the maturity and awareness of the user base. Of course, it can still be an inconvenience for testing, but that's a different issue. -- Kevin Grittner EDB: 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
