It's the WAL. Files will be 16MB in size and you will have several (I think 3 is the minimum). If you have a large update that can increase. See the checkpoint_segments setting if you think that's something you'll do frequently. If you are using WAL-based replication you could have lots if the archive command keeps failing. -- Richard Huxton Archonet Ltd -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
