Shall we add a JIRA prefix here? SPARK-31975: ...

assertAnalysisError(testRelation2.select(RowNumber()),
Seq("Window function row_number() requires an OVER clause."))

assertAnalysisError(testRelation2.select(Sum(RowNumber())),
Seq("Window function row_number() requires an OVER clause."))

assertAnalysisError(testRelation2.select(RowNumber() + 1),
Seq("Window function row_number() requires an OVER clause."))
