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.

Subject: [ADMIN] Recommended number of connections
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?
