I have looked into plpgsql-unify-loop-rc-code.patch. I have two questions: - how do currently existing coverage tools display coverage for such a large macro? I expect DEFINE's to be treated as comments. I've looked into https://coverage.postgresql.org/src/port/qsort.c.gcov.html and on line 70 I see a similar multi line define that is yellow in coverage, not counted at all. I think that "higher coverage" effect you are seeing is mostly due to code being hidden from coverage counter, not actually better testing. Another thing I see is that most define's are in .h files, and they're also not in coverage report mostly. - can this macro become a function?
