Subject: Attached is a fairly sizeable update to contrib/dblink. I'd love to
 get review/feedback if anyone is interested and can spend the time. But I'd
 also love to get this committed and address changes as incremental patches
 ;-), so if there are no objections, please apply.

Below I'll give a synopsis of the changes. More detailed descriptions
are now in a new doc directory under contrib/dblink. There is also a new

dblink.test.sql file which will give a pretty good overview of the
functions and their use.
