I am on Rails 3 with Postgresql

As a first step, try doing as instructed.  
gem install activerecord-postgresql-adapter

If that doesn’t work check back with more info.

Yup…I did the same thing but the msg is the gem can’t be found in any  
repository

So, I am back at the same point…

Had that problem before too. Sometimes it’s a firewall issue. Sometimes  
means the code’s been moved to github. Google the gem name and see what  
you  
come up with.

HTH,
