--------------------------------------
Issue Type: Sub-task (was: Bug)
Parent: HAWQ-1404
> Do not use StatsAccessor when column specified in SELECT clause
> ---------------------------------------------------------------
>
> Key: HAWQ-1431
> URL: https://issues.apache.org/jira/browse/HAWQ-1431
> Project: Apache HAWQ
> Issue Type: Sub-task
> Components: PXF
> Reporter: Oleksandr Diachenko
> Assignee: Oleksandr Diachenko
>
> StatsAccessor should be used only for queries like COUNT(*) and not
> COUNT(column) because we use file-level statistics, which has a total number
> of rows, not just number of not-null values.
