I see that Robert just committed support for a
parallel_leader_participation GUC. Parallel tuplesort should use this,
too.
It will be easy to adopt the patch to make this work. Just change the
code within nbtsort.c to respect parallel_leader_participation, rather
than leaving that as a compile-time switch. Remove the
force_single_worker variable, and use !parallel_leader_participation
in its place.
The parallel_leader_participation docs will also need to be updated.
