I was asking on the pyPgSQL list whether the PQrequestCancel() would allow
that if a user submitting queries from Python closed the Python shell, the
query would be cancelled (a la ^C in psql). This led me to:
If the connection from which a synchronous query
("libpq->connection.query()") was submitted is closed, should libpq assume a
PQrequesCancel() and cancel the query at the same time? Isn't this the
analog of ^C in psql?
Thanks,
Murthy

Libpq has:
PQrequestCancel()
Where else did you want it?
