**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** As a user of the DataFusion library for SQL parsing and logical query planning, I would like to be able to produce a valid logical plan from a SQL query containing an `EXISTS` subquery instead of failing with `Unsupported ast node Exists`. Example query: `SELECT * FROM a WHERE EXISTS (SELECT * FROM b WHERE a.id = b.id)` **Describe the solution you'd like** The SQL should parse without error and produce a valid logical plan. **Describe alternatives you've considered** None **Additional context** This is a subset of issue https://github.com/apache/arrow-datafusion/issues/123 which aims to add full support for `EXISTS`, including a physical plan. -- This is an automated message from the Apache Git Service.
