Enabling non-privileged postgres users to run specs

Browse Source 
Addressing issue #245.

A combination of fixtures and foreign key constraints requires the postgres
user to be superuser. Otherwise an attempt to disable constraints fails.
This got fixed in Rails 4 and this patch brings the same behaviour back to
Rails 3. It will allow us to run the specs with a nosuperuser postgres user.
