Remove unstable test case added in commit 5935917.

tglsfdc · tglsfdc · commit 776a2c887480 · 2019-12-11T18:53:53.000-05:00
The buildfarm says this produces some unexpected output with force_parallel_mode = regress. There's probably a bug underneath that, but for the moment just delete the test case to make the buildfarm green again. (I now notice that the case had also failed to get updated to follow commit d52eaa0, which made plan_cache_mode = force_generic_plan prevail throughout partition_prune.sql; it was thereby managing to break a later test. When/if we put this back in, *don't* include the SET and RESET commands.)
