These are new concepts as of Postgres 18 (aka only on HEAD), chosen
mainly to match with the internals of pg_stat_statements as far as I
recall. Doing the same here would not hurt, but it may be better
depending on the cases to rely on a start/end. I suspect that
switching from one to the other should not change much the internal
squashing logic.
