To my regret, I could not find such tests that week, so I decided to try
later, after reviewing my benchmark running infrastructure.
But for now, as Postgres Pro company graciously shared the benchmarking
infrastructure project [1], it's possible for anyone to confirm or deny my
results. (You can also see which tests were performed and how.)
Having done one more round of comprehensive testing, I still couldn't find
winning tests for commit 3c6fc5820 (but reassured that
test s64da_tpcds.query87 loses a little (and also s64da_tpcds.query38)).
So it seems to me that the tests I performed or their parameters is not
representative enough for that improvement, unfortunately.
