Log message:
Back off previous patch to skip projection step in scan plan nodes,
in the case where the node immediately above the scan is a Hash, Sort,
or Material node. In these cases it's better to do the projection
so that we don't store unneeded columns in the hash/sort/materialize
table. Per discussion a few days ago with Anagh Lal.
