Subject: [PATCH] Added integer width check to PostgreSQL::Quoting

Given a value outside the range for a 64bit signed integer type
PostgreSQL will treat the column type as numeric. Comparing
integer values against numeric values can result in a slow
sequential scan.

This behavior is configurable via
ActiveRecord::Base.raise_int_wider_than_64bit which defaults to true.
