> this capability is to carry over some good ideas from
> https://issues.apache.org/jira/browse/MADLIB-1038
> Candidate improvements:
> * output column naming options
> * adding an ‘*’ option and list of features to exclude
> * pivot more than 1600 column limit, i.e., most MADlib algos take array input so pivot should support array output
> * Support non-STRICT functions in Greenplum and HAWQ; this was removed in 1.9.1 since it is not handled correctly.  Does work OK for Postgres.
> * others???
