Rails Ruby on Rails

I pulled rails 3 from commit 3859828d89d378986af0fc2390608b00aad5e912 and got 1 error when running "rake test_postgresql" from the activerecord folder. The exact test that fails is finder_test.rb. To quickly reproduce the failure, run:

rake test_postgresql TEST=test/cases/finder_test.rb

Here's the entire output of the failure.
