I think that every effort should be made so that the on-disk struct- ure (ODS) doesn't have to change when tablespaces is implemented. I.e., oid-based files live side-by-side with tablespaces. At a minimum, it should be "ok, you don't *have* to do a dump/restore to migrate to v7.7, but if you want the tablespaces that are brand new in v7.7, you must dump data, and recreate the schema with table- spaces before restoring". -- ----------------------------------------------------------------- Ron Johnson, Jr. ron.l.johnson@cox.net Jefferson, LA USA "(Women are) like compilers.
