      Description

      The OpenCSVSerde produces a CSV with all its columns quoted 

      no matter of they type or if the string columns contain a separator or not.

       

      The problem is some readers (such postgresql) are not compatible with

      such CSV, in particular when bulk loading them thought COPY statement.

       

      I propose a new CsvSerde, based on a Univocity Parser (wich is used by Apache Spark)

      that has been described a 2 times faster thant OpenCSV. https://github.com/uniVocity/csv-parsers-comparison . This new CsvSerde whould only quote columns when needed.
