That's almost certainly not going to happen. I'm not aware of anyone pursuing that nor has there been any discussion on hackers. In other words, I wouldn't bet on that being something that's going to happen as there's seemingly very little interest in it among those who are developing PG and it'd be an awful lot of work for what seems to be very little actual gain. > >Generally speaking, I discourage having lots of databases under one PG > >cluster for exactly these kinds of reasons. > > It's just two... :) > > > PG's individual clusters are relatively lightweight, after all. > > But require a new port, and Enterprises have Processes that must be followed.
