Hi ,
    Does any one know how I would get a list of users currently connected to a
postgres database? In Oracle, I could select from the vg$sessions table. Is
there a corollary table in Postgres?

You can view all the database activity by:

select * from pg_stat_activity;

I am not sure about users, but i guess this should serve the purpose:

select COUNT(DISTINCT(client_addr)) from pg_stat_activity;

SELECT usename FROM pg_stat_activity WHERE datname='databasename'

There's many other connection statistics in pg_stat_activity as well,
such as IP address, current query...
