The choice of schema/database is an important one. If you get it
wrong, you are in major difficulty. In many cases schemas would be a
better choice, but not in all cases. So I'm interested in solving the
problems for people who have multiple databases on same server.
dblink is the only solution, but its very poor way to do this when we
have 2 databases on same server.
My thinking is that reaching out to multiple databases is actually
mostly easy, except in a few places where dbid is hardwired into the
backend.

Separation of databases is fine. I have no intention to change that,
as long as the user wishes that.
