No, I haven't tried that - I wasn't aware of pg_filedump. What's tricky is that when the build detects a failure, it deletes the output directory (so we don't get left with a half-built db) so I'll have to fiddle with it.... I just downloaded pg_filedump from the redhat site, so I'll play around with it, and report back if/when I find anything.
