I have attempted to make the custom format transportable (at least as transportable as pg_dump). If anyone has a 64 bit machine with weird byte order I'd love them to test restoring a backup made on another machine. If it does not work, I am happy to make it work (at least as well as pg_dump works). It just occurred to me that I may be missing something...do you mean you would prefer to avoid the 'COPY' commands as the backup technique? If so, I think that's best left to somebody else (or me, but not now, and probably not until the WAL is implemented). Also, defining your own output format is pretty easy; the new code defines a top level interface (for pg_dump and pg_restore) and an archiver interface (for output file formats), if you really want a different format. ---------------------------------------------------------------- Philip Warner | __---_____ Albatross Consulting Pty.
