Well, actually this is not possible. (And has nothing to
do with pgadmin) however, in the contrib directory
of your database there is dblink, which can issue queries
to other (also remote ) postgres databases.

You should avoid such constructs as much as possible.
Maybe slony replication of that other table is feasable?
Who knows.. it really depends on your application.

^ ^ ^ you should tell your company lawyer such a statement is nonsense
and even more in mailinglists :-)

I can think of numerous examples where someone might want to run a
query against databases on different databases or servers.
I don't think it has anything to do with design.

You might think it is better to move the data together before running
the query, but that takes a lot more time and effort for a one time
query.

As food for thought, do you think dblink was created for idiots who
don't know how to design a database and it has no real purpose for
those who actually know how to do proper design?

As an aside, Vivekananda, your questions (all of the recent ones) belong on the pgsql maillist
and not on the pgadmin maillist and you shouldn't be emailing the
pgadmin owner as well.

You should never design a database structure that requires you to access a completely different database.  The best way
tokeep data separate, yet give your users access to the uniqueness of a separate structure, is to create different
schemas.

You may wish to spend some time re-thinking the structure of your DB system.

Hope this helps,

And he probably shouldn't be posting html either!

Couldn't agree more.
