Hi,
I'm trying to run multiple postmaster instances on the same  machine. I
want to start and stop the server
from inside of my application. However, for each of these instances, I
want to specify a different "storage cluster".
I understand that I can do that while initializing (initdb -D <path>).
But after I start multiple instances, how do I let psql
know which server I'd like to connect to. Since they all run on the same
port, whenever I run psql it only connects to the last server for which
I called initdb on. Since psql doesn't take -D <storage directory>, I'm
not sure how I can accomplish this.

Any help is welcome.

Thanks
-BG
