Um ... how does that solve the claimed problem exactly?

This particular choice seems remarkably *un* friendly, since two dumps
from different DBs will inevitably not share the same OIDs, making it
practically impossible to compare them even if they are logically
identical. But even without the choice to use OIDs in the filenames
I'm unconvinced that file-per-object is a good idea in any way shape or
form.
