But that's the vital bit. Without being able to extend relational
integrity checks across database boundaries you're not really getting
something that's general-use.
Without that it's not really worth extending syntax - dblink() offers a
solution to the limited cases available.
If you manage to come up with an efficient multi-master replication
system though, please let us know :-)
