Labels: (was: TriagePending)
> Improve documentation / Handling of quartiles/ntiles in Postgres
> ----------------------------------------------------------------
>
> Key: MADLIB-808
> URL: https://issues.apache.org/jira/browse/MADLIB-808
> Project: Apache MADlib
> Issue Type: Request
> Reporter: Caleb Welton
> Assignee: Rahul Iyer
>
> Currently the Summary() function will silently decide not to calculate
> quartile values on Postgres or GPDB < 4.2 due to the lack of support for the
> SQL Standard PERCENTILE_CONT() function on those platforms/versions.
> This limitation should be clearly documented and a warning should be produced
> if these statistics are requested on a platform that does not support them.
