Title: update in establish_connection override to fix issue #114

The tests still pass for mysql and postgresql using activerecord 3.2.6. Also this works fine with rails 3.2.6 on Heroku.
There are a few differences between activerecord 3.2.6 and the methods overridden in composite_primary_keys below establish_connection but I didn't modify them. Why did they have to be overridden since there doesn't seem to be any addition related to composite_primary_keys ?
