Alexander Kuzmenkov f1e103fab1 Fix DISTINCT ON queries for distributed hyperatbles
Previously, we would push DISTINCT ON down to the data nodes even when
the pathkeys of the resulting paths on the data nodes were not
compatible with the given DISTINCT ON columns. This commit disables
pushdown when the sorting is not compatible.

Fixes #3784
