def check_int_in_range(value)
  if value.to_int > 9223372036854775807 || value.to_int < -9223372036854775808
    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
