We tried everything...vacumm works. The problem is that updates need more space becouse datas is not overwritten in the same space... it seems that when there is huge update db grow to create space necessary ...700 Mb every time and than vacuum works but only since next update! and db grow 700Mb more and 700 Mb more.... It seems a bug Sorry for my english that isn't so good :( -- View this message in context: http://postgresql.1045698.n5.nabble.com/DB-become-enormous-with-continuos-insert-and-update-tp3237814p3237903.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
