That would shut down the whole database, which is likely not what you
want.  The best way to cancel a runaway query is to cancel it, ie,
send a cancel request from the client (cf. control-C in psql, dunno
whether the ODBC driver supports this).  If you are logged into the
postgres or root account on the DB machine, you can get the same
effect with "kill -INT pid-of-backend".  (not pid-of-postmaster)
