Also, it's good to make at leas

reason I ask is I was wondering what (if any) is the

Beats me. WE are not requesting a "select *" at all in the VB code. We

Hi,
I was just wondering if postgresql supports queries between servers in

Let's say server A can run a query against server B... something like:
server1 running a SELECT * FROM server2.table
or joins
SELECT A.name, B.name FROM server1.table A, serve
