> Current, all statements in sql client are parsed via regex matching, which
> has many limitations, such as it can't handle comments. To avoid that
> limitations, we should try best to use sql parser to parse a statement. There
> are many statement can't be handle by sql parser, such as: set, reset. so
> they are still handle through regex matching.
> statements handled through regex matching:
> quit, exit, clear, help, desc, explain, set, reset source, show modules
> statements handled through sql parser:
> show catalogs, show databases, show tables, show functions, use catalog, use,
> describe, explain plan for, select, insert, DDLs
> note: we keep `explain xx`, and also support `explain plan for xx`
