+1. I think Noah's comment additions constitute useful and helpful information, but I too am doubtful about the characterization of the situations in question as bugs. I don't see what the evidence for that is, especially given that it's quite hard to predict how the code might change in the future. However, to reiterate, a more neutral position of the same facts would get my vote. -- Robert Haas EnterpriseDB: 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
