Well, I do have a copy of the corrupted database/file, if that's
what you mean. I rebuilt 7.3.4 source (which I don't normally
delete) so I could build pg_filedump 2.0, but then pg_filedump
wouldn't build. Not sure why; I didn't have the luxury of
digging deeper. Maybe I can find a pg_filedump laying around
somewhere here, or sort out the build issue...
