Thinking more about it, I see your point now. HEAP_LOCKED_UPGRADED is
not a direct combination of the other flags and depends on other
conditions, so we cannot make a combination of it with other things.
The three others don't have that problem.

Attached is a patch to fix your suggestions. This also removes the
use of HEAP_XMAX_IS_LOCKED_ONLY which did not make completely sense
either as a "raw" flag. While on it, the order of the flags can be
improved to match more the order of htup_details.h

Does this patch address your concerns?
