That's definitely where we are now. Had a call with a customer today where I said "it's OK, its only out by 3 orders of magnitude, it gets worse than that". 9 hour query, with substantially incorrect EXPLAIN. I don't claim to have any/all of the answers myself, but this needs attention very badly. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
