exception = <<~ERROR
Provided value outside of the range of a signed 64bit integer.
PostgreSQL will treat the column type in question as a numeric.
This may result in a slow sequential scan due to a comparison
being performed between an integer or bigint value and a numeric value.
To allow for this potentially unwanted behavior, set
ActiveRecord.raise_int_wider_than_64bit to false.
ERROR
raise IntegerOutOf64BitRange.new exception
