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.
