pg_cancel_backend(pid int) to kill. You need to know the pid, you can
obtain the pid from pg_stat_activity.
To log slow querys you can set log_min_duration_statement to a propper
value, in ms. All querys with an execution time more than that logged.

Oh, and please don't post to several lists at once - this clearly isn't
a hacker-related question.

Please don't cross-post to multiple mailing lists. And pgsql-hackers is
not the correct list for basic usage questions. And long end-of-mail
disclaimers are not generally appreciated.

See the user manual on administration functions, pg_cancel_backend in
particular:
http://www.postgresql.org/docs/8.2/interactive/functions-admin.html
Basically you issue a "SELECT * FROM pg_stat_activity", or plain ps to
find out the pid of the backend executing the long running query, and
then use pg_cancel_backend (or kill -INT) to cancel it.

Using the log_min_duration_statement configuration variable.

First. please do not cross-post like this. Pick the correct list and use it.
Second, this query definitely does not belong on the -hackers list.
Third, please find a way of posting to lists that does not include a
huge disclaimer and advertisements. If that is added by your company's
mail server, you should look at using some other method of posting such
as gmail.
Fourth, please read our excellent documentation. It contains the answers
to your questions, I believe.
cheers
