Re: [postmodern-devel] OSX 10.6.8 Intel - SBCL 1.0.54 The function cl-postgres::write-uint4 is undefined.

cl-postgre::write-uint4 undefined (messages.lisp)

If this is the actual error message, then your source is most likely corrupted somehow (the symbol is "cl-postgres::write-uint4"). This is definitely not a problem with your PostgreSQL setup. The write-uint4 function should be defined by cl-postgres/communicate.lisp (through a macro). Best, Marijn
