I would tend to agree, there are numerous times being able to do a cross
database query without the hassle of DBlink
would be extremely handy.  I could also see it being valuable in a data
warehouse type situation.

I know it can be done in M$ SQL server using .. notation and I bet you
can do it in DB2 and Oracle.
you can even do it in MySQL, in MySQL it's their way of implementing
schemas.

Considering all these other DBs can do it, doesn't it make sense to at
least put it on the radar for Postgresql?

Just my 2 cents....
