Supporting dialects in the parser

[eyalleshem]

Hi ,

Currently the lib support different databases (postgresql-sql, mysql , etc .. ) dialect only in the tokenizer.

My question is - if there was any discussions/plans about supporting per-db dialects also in the parser (or do you you think it's god idea to start such discussions )?

Where most of the DB's support ANSI sql , when it's come to more advance features like json-parsing - There is great variability between the different databases
