Thanks all. I should add a few things to this question:
The queries would always be SELECT queries. Users would be doing the query
from apps like NCR QueryMan or Crystal Reports. While I could connect to
my box via the command line and kill the PID, I hoped there was a way to
utilize the quit query capabilities both of these apps provide.

Better is just to send SIGINT to the individual backend running the
query. This is equivalent to the client having made a QueryCancel
request.

No more dangerous than any other forced database crash ... which is what
you will get if you kill a backend process ...
