I've moved discussion of this GiST bug over to the old 2021 thread
where I first raised concerns about the issue:
https://postgr.es/m/CAH2-Wz=jjiNL9FCh8C1L-GUH15f4WFTWub2x+_NucngcDDcHKw@mail.gmail.com
The GiST bug is actually causally unrelated to the bitmap index scan
bug under discussion, despite the high-level similarity. Seems best to
keep discussion of GiST on its own thread, for that reason.
