Here's the latest version of this patch. It removes all use of
background_psql(). Instead it uses libpq's async interface, which seems
to me far more robust. There is one remaining use of interactive_psql(),
but that's reasonable as it's used for testing psql itself.

I spent yesterday creating an XS wrapper for just the 19 libpq functions
used in Session.pm. It's pretty simple. I have it passing a very basic
test, but haven't tried plugging it into Session.pm yet.
