Okay, applied the main fix down to v13 then.

After sleeping on this point, I have finished with this idea for tests
down to v17, adding more coverage for v18 with the GUC vacuum_truncate
and the "auto" mode of index_cleanup, while on it.  v16 and older
branches don't have tests, but I have checked the sanity of the two
code paths using the tests attached for vacuum.sql and
pgstattuple.sql, at least.  Two truncation tests for the "false" cases
were actually unstable.  Sometimes the truncation may not happen even
with an aggressive VACUUM.  Anyway, it is enough to check the true
case for the two code paths patched, even if it may not happen at
100%.  I did not notice a problem with the index_cleanup case as long
as we had enough pages in the TOAST btree index, requiring some
runtime to load the entries, so the cost was annoying.

Attached is the remaining patch for HEAD, planned once v19 opens, and
the tests I have used on the back-branches as a txt to not confuse the
CI, for reference.

Subject: [PATCH v5] Refactor handling of VacuumParams

This adds a couple of const markers, while removing pointer uses of
VacuumParams to force the following policy among all the VACUUM-related
calls: do not touch the values given by the caller.

This patch is for HEAD.
