Another noticeable, but not critical performance degradation is revealed by
query 87 from TPC-DS (I use s64da-benchmark):
https://github.com/swarm64/s64da-benchmark-toolkit/blob/master/benchmarks/tpcds/queries/queries_10/8...
With `prepare_benchmark --scale-factor=2`, `run_benchmark --scale-factor=10`
I get on master:
2023-05-10 09:27:52,888 INFO : finished 80/103: query 87 of stream 0: 2.26s OK
but on REL_15_STABLE:
2023-05-10 08:13:40,648 INFO : finished 80/103: query 87 of stream 0: 1.94s OK
This time `git bisect` pointed at 3c6fc5820. Having compared execution plans
(both attached), I see the following differences (3c6fc5820~1 vs 3c6fc5820):

From the commit message and the discussion [1], it's not clear to me, whether
this plan change is expected. Perhaps it's too minor issue to bring attention
to, but maybe this information could be useful for v16 performance analysis.
