What are the "maximum" amount of "connections" allowed to "postgres"? and what would be a resonable amount of connection/processes to see based on user connections?

The maximum number of Postgres connections you can have may be
controlled by adjusting the max_connections PG parameter based on your
anticipated connections needs and requirements.
Make sure that your Kernel's related parameters are also configured
properly to accommodate your max_connections settings (e.g, in Linux,
SEM* kernel's parameters) when increasing the max_connections parameter.

That really depends on what you're doing with it. If each connection
is doing a simple transaction on a small indexed set, then you can
probably have hundreds of connections open on an even modest machine.
OTOH, if you're running reports across hundreds of megs with a large
work_mem setting then you might be best with only a few dozen or so
connections.
So, what are ya doing and how many users are you supporting at once?
