Amazon Redshift adapter for ActiveRecord 4 (Rails 4). I copied PostgreSQL driver from ActiveRecord 4.0.0 and modified for Redshift. "Barely works" patch was borrowed from fiksu/activerecord-redshift-adapter.
I know Redshift driver already exists (https://github.com/fiksu/activerecord-redshift-adapter), but it currently supports only ActiveRecord 3. Also, AR4 code is magnifically different from AR3 code because of file separation, patching does not work well. I want to use Rails 4 with Redshift NOW, so I wrote this driver. If anybody write better Redshift driver which works with ActiveRecord 4, I abandon this driver.
