psql connect_timeout feature

I've dug through the docs and peeked at the source and found no way to
specify a connect_timeout so:

1. Did I, in fact, just overlook something?

2. We would find it extremely useful to have this option. Would anyone else?

3. Alternately, what about adding a "raw connection string" feature to
psql. The supplied string would be passed straight to the PQconnectdb
function and allow access to all connection parameters without the
necessity to keep adding individual command-line options for each
individual parameter.

Cheers,
Steve
