Обсуждение: database clustering

Hello,
I am planning a postgres database cluster.  Each database will be on it's own machine and I wanted to enable one as the
frontendto the rest.  This is so that applications do not need to know which database contains what data.  Is there a
wayto configure postgres to communicate to other dbs via sql so as to be transparent to the user?  I know this can be
donein Oracle though I'd rather not go through that experience if I do not need to. 

Thanks,

-Joe

Perhaps this is something that would benefit from the use of sql relay:

    http://sqlrelay.sourceforge.net/

Very neat ideas, and might be another approach for your problem.

I have looked at this and this is not what I was looking for.  Using this the application will need to figure out how
tomerge records.  I was looking to be able to use something like the oracle syntax of host:database:schema:table within
sqlto service the queries.
