Feature Request: "Unparsing"

[abhillman]

i.e. for a given dialect, go from an AST -> SQL

[AugustoFKL]

@abhillman I don't think this is feasible in the near future.

I think that's more feasible to be done in another project, as a side-project of someone, than as a part of this crate.

That would require one of the two following approaches:

• Re-structure the AST and have once for each dialect (e.g., SelectPostgresql, SelectAnsi, etc.); or
• Have a dialect-specific implementation of to_string() of the AST.

Either way, it's a big change, and the current state of the project is basically stable, so huge changes aren't prone to be accepted.

The problem with the second solution, IMHO, is that this would be an expansion in a feature completely new, which would require a big help and supervision from maintainers, which isn't feasible right now.
