Worth noting that Lukas Fittl made a point of prominently highlighting
the issue with how this works when he explained the Postgres 17 nbtree
work:
https://pganalyze.com/blog/5mins-postgres-17-faster-btree-index-scans
And no, I wasn't asked to give any input to the blog post. Lukas has a
general interest in making the system easier to understand for
ordinary users. Presumably that's why he zeroed in on this one aspect
of the work. It's far from an esoteric implementation detail.
