I like this idea, in general, also. Taking that to the next level would
be figuring out how you can do the same kind of thing through an
interactive psql session where the user running the query doesn't need
access to the database server or PG log files...
We can send a 'cancel query', how about a 'report on query' which
returns the plan and perhaps whatever other stats are easily available?
Thanks,
