I am not facing any issues, but yes I want to have optimal performance for SELECT and INSERT, especially when I am doing these ops repeatedly. Actually I am porting from Oracle to PG. Oracle starts a lot of processes when it needs to run many schemas. I do not think PG would need much more resources (mem, cpu) if I go for different database for each process..? Also, is there any limit on number of databases I can start using a PG server?
Best Regards, Divakar

Anyway it's hard to predict what kind of performance issue he's facing and whether two clusters would fix it.
