Subject: PostgreSQL (Postgres-pr) + Rails = Unexpected EOF error?

 I'm running XP, Ruby 1.8.2RC3, Rails 0.8.5, PostgreSQL 8BetaRC3, and
Postgres-pr (new Ruby library). 

My problem is that I'm getting an "Unexpected EOF error on client
connection."

Does anyone perchance know what's causing this? It happens both on Webrick
and Apache.

Regards, Abe

P.s. I have not yet successfully completed a connection to the PostgreSQL DB
yet.

Hm, ParseError is a class in postgres-pr/message.rb. But I don't understand
the error message "superclass mismatch". Can you update to
0.2.2 which puts all stuff into a module PostgresPR. Maybe it was a
namespace issue?
