I'm resuming work on this project, now targeting Postgres 20.

Attached is v25, which I'm posting now to keep CFTested happy and to
ensure the patch set applies cleanly against the master branch. There
are no substantive changes here compared to v24.

I would like to get the first patch committed soon-ish (the one that
revises the table AM by making index scans use a higher-level,
slot-based interface). Maybe in the next 4-8 weeks. That piece is much
simpler than the later ones.
