Having "file", "file.1", "file.2", and such is routine; that is the normal handling of tables that grow beyond 1GB in size. If there is actually 3GB of data to store in the table, then there is nothing to be 'fixed' about this. There is no duplication of data; each of those files contains distinct sets of tuples. First question... Are you vacuuming the table frequently to reclaim dead space? If that table is heavily updated (e.g. - via DELETE/UPDATE; mere INSERTs do NOT represent "updates" in this context), then maybe there's a lot of dead space, and running VACUUM would cut down on the size. If you're running VACUUM often enough, then there's nothing wrong, and nothing to be done. You're simply observing how PostgreSQL handles large tables. -- let name="cbbrowne" and tld="ntlug.org" in name ^ "@" ^ tld;; http://cbbrowne.com/info/multiplexor.html "Funny, the only thing that makes me go Keanu about Microsoft is the fact that they are constantly behind the times and yet claim to be innovating." -- Steve Lamb <morpheus@xxxxxxxxxxxxxxxxxxx>
