Hi, everyone.  Alban wrote:
Which version of pg_dump did you use? The one that came with the 9.0 install or 
the one from the old 8.3 one? It should have been the first of these two.
The dump was done by someone using the old, existing system, which runs under 8.3. She complained that she was having problems (i.e., the 36-hour restore), and after we looked at it, we decided to take the file and try to import it into our 9.0 database with pg_restore 9.0, just to see what was going on.

It's quite possible that the pg_dump from 9.0 would have done a better or more intelligent job, but we can't switch it into widespread use right now. (We have 8.3 installed in a closed-box product that's physically distributed to customers.) We can mix and match 8.3 and 9.0 in the development lab, but not on a widespread scale.
