Re: how to cancel a query ?

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?
