The postgres gem (postgres (0.7.9.2008.01.28)) is not actively supported. It will not install under Ruby 1.9 as extconf.rb makes reference to a constant PLATFORM that is no longer built in to the Ruby environment. The version info (0.7.9.2008.01.28) gives a clue that this gem is no longer current.
I recommend that you go with the pg (pg (0.8.0)) as it will install and work with both Ruby 1.8 and 1.9. It is the path forward.
