Don't use it myself, but from discussion on the lists, I'd say "probably" -
don't see how it could be otherwise. You'll want to test.

Nope - just not practical. You could bring both servers to a grinding halt
very quickly trying to keep track of FKs over a network link.

Incidentally, if you don't need the two databases on different machines,
perhaps look at using schemas to separate users - that would let you have FKs
etc.
