Connections to DB

SELECT * FROM pg_stat_activity;

Note that if you turn on stats_command_string you'll also be able to see
what each connection is doing if you're connected as a superuser.

How can I view the current, persistent connections to a database? Is there
a way to do this with 'psql' or with some other PostgreSQL bundled
tool/utility (~pgsql_directory/bin), instead of resorting to the underlying
operating system commands (ie: netstat -a | grep postgres)?

I am interested in finding out the following: 1) How many connections are
there to the database? 2) How long have they persisted? 3) What is the
idle time of the connections?

Any help would be appreciated. Thanks!

Just as a little FYI, on 8.1 pg_stat_activity will show the IP address
and port as well, but only on 8.1.
