ISTM that the uses cases of various combinations of adding a default
partition, adding another partition after it, removing the default
partition, clearing out the default partition in order to add more
nondefault partitions, and so on, need to be more clearly spelled out
for each partitioning type.  We also need to consider that pg_dump and
pg_upgrade need to be able to reproduce all those states.  Seems to be a
bit of work still ...
