Rails on PostgreSQL

Occasionally I see a job description or interview where someone will mention that they're using PostgreSQL + Rails in production for some big application. I'd like to do more detailed writeups on these... but here are some that I've seen:

• Ryan Heneise writes in to say that Donor Tools runs on PostgreSQL.


• Doug Cole wrote in to confirm that the nifty real estate service estately.com runs on Rails + PostgreSQL. They use PostgreSQL full text search and PostGIS. Doug also noted that (as of 9/21/09) they're hiring developers, so, give them a holler if you're looking. You can also see a nifty PostGIS presentation they did at Seattle Tech Startups.


• Mark Tremblay adds screenlight.tv to the list.


• Nathen Harvey writes in that VisualCV is a Rails + PostgreSQL app.


• Eric Hodel says that he's using Rails + PostgreSQL on rubypan.org. He uses PostgreSQL FTE via the texticle gem.


• This job advertisement indicates that Yammer is using Rails with PostgreSQL. From that advertisement, they're also using PostgreSQL's full text search.


• Heroku provides each Rails app with a PostgreSQL database. I've googled all over for more information but haven't dug up any other interesting details, although I bet there's some neat stuff going on there.

That's all that come to mind at the moment. If anyone has more details on any of these, or more examples, please let me know - would be great to have some more detailed information!
