Does anyone feel that it's a bad idea that list entries are never reclaimed? In the worst case a transient load peak could result in a long list that permanently adds search overhead. Not sure if it's worth the extra complexity to delete a list cell that's no longer needed, rather than leaving it present and empty. > Do we consider this a bug fix, to be backpatched? Yes, definitely. I think I'd like to have a go at coding it the other way (with release of list entries), just to see if that comes out cleaner or uglier than this way. If you don't mind I'll pick this up and commit whichever way turns out better. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
