>
> 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.
