Dylan Guedes created SPARK-28500:
------------------------------------

             Summary: adds support for `filter` clause
                 Key: SPARK-28500
                 URL: https://issues.apache.org/jira/browse/SPARK-28500
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dylan Guedes


Definition: "The {{filter}} clause extends aggregate functions ({{sum}}, {{avg}}, {{count}},
…) by an additional {{where}} clause. The result of the aggregate is built from only the
rows that satisfy the additional {{where}} clause too." [source|[https://modern-sql.com/feature/filter]]

Also, PgSQL currently support `filter` while Spark doesn't.
