I want to have one backend terminate the transaction on another
backend as soon as practicable. If a query is active, it would be
best if it was canceled. It appears that if it is "idle in
transaction" there is a need to wait for the next request. It would
be a big plus for the backend requesting the cancellation to be able
to specify the SQLSTATE, message, etc., used by the other backend on
failure.

OK. While browsing around, I'll try to think of an alternative
approach, but this is new territory for me -- I've been learning
about areas in the code at need so far....
