Choose a convention. At the moment, the first source table provides more
characteristics to the target than do the other sources, and that could
be true for OIDs also. I would be inclined to have the logic be that if
*any* source table has OIDs, then the target gets them. Unless it was
explicitly specified using the WITH/WITHOUT syntax of course.

Right. There is no problem coming up with consistant semantics, though
there may be a problem getting a consensus on what those should be.
In the meantime we have broken compatibility with the previous release
(since targets are created without OIDs) and should think about fixing that.
