[GENERAL] Number of Connections

[Steve McAtee]

Hello,

I'm a bit new to postgres.  Is there anyway to tell the current number of
connections on a database or server?  I'm having a connection closing
problem and would like to debug it somehow.  I know on Sybase you can check
a sys table to determine this.  Not familiar with how to do this on
Postgres.

Please advise and thank you.
