**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** PostgreSQL supports the SQL `Filter Clause` which is a clause that filters certain rows based on the defined row expressions before an aggregation is performed. Currently Datafusion does not provide a mechanism for parsing those clauses. See [Filter Clause](https://modern-sql.com/feature/filter) for more in depth details on the clauses behavior. **Describe the solution you'd like** The `datafusion::logical_plan::plan::Aggregate` struct should include a new member Ex: `pub filter_expr: Vec<Expr>` which contains the filtering expressions that could be applied by the consuming engine before performing the actual aggregations that are defined in `pub aggr_expr: Vec<Expr>` **Describe alternatives you've considered** None **Additional context** Description of the syntax and functionality can be found [here](https://modern-sql.com/feature/filter) -- This is an automated message from the Apache Git Service.
