this is not your patch fault but an existing bug, i repeat that
behaviour in an unpatched source tree...

with the steps in the previous mail i canceled 2 or 3 backend before
cancell the one with the explain analyze, i execute a second time that
pg_cancel_backend and if i try to re-run the query it gets cancelled
immediately, next time it runs normally...

pg_stat_activity reports that query as running no mather what...
