                 Key: FLINK-15826
                 URL: https://issues.apache.org/jira/browse/FLINK-15826
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
    Affects Versions: 1.11.0
            Reporter: Fabian Hueske


The {{Catalog}} interface lacks a method to rename a function.

It is possible to change all properties (via {{alterFunction()}}) but it is not possible to rename a database.

A {{renameTable()}} method is exists.
