It would in stream mode, which doesn't work at all. I do agree with Roberts suggestion that we shouldn't remove file mode right away - but we should change the default. > It might be worth considering a mode that combines all those tar files > into a super-tar.

That would probably be useful, though a lot more difficult when you consider two separate processes writing into the same tarfile. But I agree that the format for "single tablespace just gimme a bloody tarfile" is quite incovenient today, in that you need a directory and we drop a "base.tar" in there. We should perhaps try to find a more convenient way for that specific usecase, since it probably represents the majority of users. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
