No, but I'd love something that can throw an SNMP event when queries are
taking too long -- or someone is idling in a transaction...

Also, is there a command to kill a specific connection at any given time?

kill(1) is the only one I'm aware of.

Cheers,

P.S. User support questions should probably be directed to a mailing
list like pgsql-general or pgsql-novice

Postgres starts a server process for each client connection. You can use
/bin/ps to show the active connection processes. The process command
string gives some information about what each connection is doing -- the
user and database being used, whether the connection is idle or processing
a query and the type of the query, as well as whether it's in a
transaction.

You can kill a connection, simply by killing the corresponding postgres
process.

% ps -auwwx | grep ^pgsql

pgsql 52081 Tue03PM 0:02.27 /usr/local/bin/postmaster (postgres)
pgsql 52082 Tue03PM 0:00.20 postmaster: stats buffer process (postgres)
pgsql 52084 Tue03PM 0:00.98 postmaster: stats collector process (postgres)
pgsql 65062 5:05PM 0:04.25 postmaster: ocrow ocrow [local] SELECT (postgres)
pgsql 65071 5:05PM 0:00.04 postmaster: ocrow ocrow [local] idle (postgres)

In this list process 65062 is executing a select query, and 65071
is idle.
