FYI, we call it PostgreSQL or pgsql around here.
The maximum number you can create is much more than the maximum number
you like want to create. What are you looking at doing? Might
connection pooling be a good match for that?
I have session db servers that keep ~800 persistent connections open
for small single table queries and they do just fine. I've tested
thousands of connections with decent performance. However having lots
of open connections can lead to "thundering herd" problems and is
generally suboptimal.
