I no longer observe these after applying these two patches by Amit
Kapila:
avoid_restricted_clause_below_gather_v1.patch
Message-ID: <CAA4eK1Ky2=HsTsT4hmfL=EAL5rv0_t59tvWzVK9HQKvN6Dovkw@mail.gmail.com>
prohibit_parallel_clause_below_rel_v1.patch
Message-ID: <CAA4eK1L-Uo=s4=0jvvVA51pj06u5WdDvSQg673yuxJ_Ja+x86Q@mail.gmail.com>
I guess these failed assertions are fallout from the workers executing
forbidden plans without the patches.
