Hello, Your README states that part of the project is BSD licensed, but it is actually PostgreSQL license  according to the BSD file content. Could you please clarify the licensing?
The README file for ruby-pg says: You may redistribute this software under the terms of the Ruby license, included in the file "LICENSE". The Ruby license also allows distribution under the terms of the GPL, included in the file "GPL".
This is no longer the case, as of Ruby 1.9.3, which is dual-licensed with the 2-clause Simplified BSD License rather than the GPL. The README and LICENSE files should be altered to reflect this change.
