hi, all The PostgreSQL has a option: backslash_quote. It can be on, off or safe_encoding. How to set it to ingore back-slash check? The command: INSERT INTO table_name VALUES(..., '\\', ...); always get a warning message whatever it is. If use E'\\', value will be saved as '\' in database. Has a approach to let PostgreSQL conside back-slash as common char?
