# File activerecord/lib/active_record/connection_adapters/postgresql/quoting.rb, line 28 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 end end

unescape_bytea(value) 链接
将数据库中的 bytea 输出还原为它表示的二进制字符串。注意:这不是 escape_bytea
的逆运算!这只能用于数据库驱动程序转义的二进制输出。
