Robert Haas cafe105655 Allow SIGINT to cancel psql database reconnections. 
After installing the SIGINT handler in psql, SIGINT can no longer cancel
database reconnections. For instance, if the user starts a reconnection
and then needs to do some form of interaction (ie psql is polling),
there is no way to cancel the reconnection process currently.

Use PQconnectStartParams() in order to insert a cancel_pressed check
into the polling loop.
