Actually look at the coverage reports:
https://coverage.postgresql.org/src/backend/optimizer/prep/prepunion.c.gcov.html
1742 : /*
1743 : * If the partitioned table has no partitions or all the partitions are
1744 : * temporary tables from other backends, treat this as non-inheritance
1745 : * case.
1746 : */
1747 4920 : if (!has_child)
1748 0 : parentrte->inh = false;
1749 4920 : }
expand_partitioned_rtentry() never disables this flag on recursive calls
with a multi-level tree. Could it be possible to get a test which
closes the gap?
