Awesome. Given that their services look Ruby-centric, maybe they could take over PL/Ruby and point out that this would allow people to write their stored procs in Ruby too.
An update to PL/Ruby would be great.
It doesn't appear to have been updated for a couple of years or use Ruby 1.9 : https://github.com/knu/postgresql-plruby . There is also a newer fork : https://github.com/globegit/postgresql-plruby , which does appear to be worked on.
