Here is an updated patch set.
- 0001 is unchanged.
- 0002 contains the module that tests the correct behavior of
get_actual_variable_range for non-returning ordering indices.
It contains a copy of the btree handler function with its index-only
capabilities removed. If you apply patch 0002 on master without 0001,
you will see that the test returns an error (ERROR: no data returned
for index-only scan) as it tries to use the index in
get_actual_variable_range, which shouldn’t be the case.

Best,
