This stuff sounds pretty nice. However, have a look at this report:
https://codecov.io/gh/postgresql-cfbot/postgresql/commit/2aa632dae3066900e15d2d42a4aad811dec11f08
it seems to me that the new code is not tested at all. Shouldn't you
add a few more tests?
I think 0004 should apply to unpatched master (except for the parts that
concern files not in master); sounds like a good candidate for first
apply. Then 0001, which seems mostly just refactoring. 0002 and 0003
are the really interesting ones (minus the code removed by 0004).
