The exact version I am using is 8.1.4 - so my version is old - good!
There is hope that upgrading will fix everything!

I see your point, but - as far as I know - there is no way of
interrupting a running query (short of exiting from the main
executable); so maybe a (large) timeout  would be a safe way of
protecting against trouble.  As to killing the connection, using a
connection pool may mitigate the problem.

Better a broken connection in a running thread than a useless thread
which cannot be interrupted!

Of course, my perspective is mainly related to web applications -
standalone applications might use other techniques.

Anyway, if you plan to support query timeouts, as you suggest in another
message, that would be perfect.

IMHO, depending on your plans, the "socketTimeout" strategy could be a
temporary fix if the "setQueryTimeout" is too far in the future.

Just my suggestions after a week of stress-testing a busy server! I love
postgreSQL and thank everybody for their efforts here!
