Actually cross database writes can also be done with dblink, but without
2PC, or something similar, it is hard to make it bulletproof.

More to the original point, there is no one (that I'm aware of) actively
working on internal backend cross database functionality such as what
the OP seems to be expecting. There has been discussion on this in the
past (see the mail archives), and there is a SQL2003 spec covering it
(see SQL/MED). Patches would be warmly welcomed ;-). If I don't get beat
to it, I might find the time and interest someday, but there is no
"expected" date of arrival.
