If you wanted to do something programatically, couldn't you define some
functions that would allow you say implement a query id, and embed a
function call in the where clause like

select getNextQueryId()

where ...... and queryStillActive(query_id) = true

Then another function could be called to kill the query either from within
the program, or externally like

stopQuery(query_id).

You probably wouldn't want to do this for every query, but if you know you
have some potentially long running queries, then....
