OK, that makes this a planner failure: we should not have allowed this
query to become parallelized.

It seems like maybe searching for individual Params is the wrong thing.
Why are we allowing it to generate a parameterized Gather path at all?
Given the lack of any way to transmit runtime param values to the worker,
I can't see how that would ever work.
