Hi, having some difficulty with OSX 10.6.8 Intel - SBCL 1.0.54 I used quicklisp (most current) to install and my debian (6.0.3) boxes are fine but my Macbook Pro (10.6.8) is having the issue. The same error is happening when I use; postgresql 8.4 or 9.1 locally (running on OSX) or remote to a debian box running 8.4 and even a VM (VirtualBox) running debian (6.0.3) on the Mac with NAT forwarding to postgres 8.4. I can connect with psql in the various configurations described for the remote connection I made the appropriate "all/all/trusted" additions to the "/etc/" files so it is unencumbered by any security. I deleted my FASLs and I tried connecting without a database running and the FASL removal and "re-load" did not solve the issue and the connect-toplevel without a database running error was what I expected. The Postgres is a "clean" install with only the ytestdb added on all systems I tested against. ytestdb is the database postgres is the user post is the password ;;ERROR cl-postgre::write-uint4 undefined (messages.lisp) I hope this information is helpful.
