             Summary: Fix ST_RemovePoint in accordance with the API document
                 Key: SEDONA-169
                 URL: https://issues.apache.org/jira/browse/SEDONA-169
             Project: Apache Sedona
          Issue Type: Bug
            Reporter: Kengo Seki


According to the API document for {{ST_RemovePoint}}, the second parameter can be omitted.
{quote}Introduction: RETURN Line with removed point at given index, position can be omitted and then last one will be removed.

Format: ST_RemovePoint(geom: geometry, position: integer)

Format: ST_RemovePoint(geom: geometry)
{quote}
But it actually fails if the second parameter isn't specified.
