v7.38.11 — read a range predicate’s bounds so a BRIN index can say which slots the scan may skip.
Lives in its own module, and is #[cold] #[inline(never)], for a
measured reason: v7.38.8’s conjunct reorder cost two shapes it did
not even touch 17 % and 20 % purely by being compiled into the file
that holds the row loop. This runs once per plan; it has no business
near that loop’s code layout.
