I'd like to know if shared accounts have mod_rails (Passenger), and if so, which version(s) of Rails can be used? For example, would I be free to install either Rails 3.0 or 3.2, or am I locked in to whatever gem is installed?
Which version of Ruby is installed on the shared accounts? Can I get RVM on a shared account? Git?
Also, is postgreSQL available on the shared accounts?
