select * from pg_stat_activity where datname='mydbname'

should get you started.

You can see all the system tables with
\dS
in psql

 pg_stat_activity
where
 datname = (

 );

Hi,

Is there any way to query the database to identify what the current
connections are (connections, sessions, or whatever you want to call
them)?

This would be something similar to oracle's v$session view.

Thanks,
Matt
