select pg_cancel_backend(procpid) solved half of my problem...at least it terminated the query for that user... but it is still holding a user connection in IDLE state....If I have too many of those, Postgres may run of out of user connections....
I already knew how to kill a connection if the connection is from the local host. But I have many remote connections coming from different machines... hard to kill with unix command "kill"... One time, I was testing to kill a particular connection on a testing machine, the entrie Postgres was brought down....
I need to find a safer, cleaner way to disconnect a user from Postgres when needed.
Thanks a lot,

From the command line on the server you can issue a kill
to do
that. From within pgsql you'd need to write a function in an
untrusted language to pull it off.
