Then move to PostgreSQL at a later date. In short, focus on learning the basics of RoR. BTW, I tend to use Sqlite3 for development and PostgreSQL or MySQL for stagging and production. Good luck, -Conrad ---

Uh, I know now about the postgresql-pr gem. Part of the confusion is that there are several PostgreSQL gems laying around. The one I used is “pg”. You will also need to drop it into Gemfiles.
