Subject: [PATCH 1/2] doc: Clarify enable_groupagg also covers Unique and SetOp
 plans

The parameter description mentioned only sort-based grouping and
aggregation plan types, but it also discourages sort-based Unique
and SetOp plans.  Mention them explicitly so users know the full
scope of the switch.
