I tweaked this patch some more (sorry):
- remove "currently" since that's not expected to be changed (right?);
- remove "especially";
- refer to "partition hierarchies" not "partitioning hierarchies";
- rewrite bit about "When partition pruning is not possible"
Also, I noticed awhile ago while grepping for "probably be fixed in future
releases" that some items under ddl-inherit-caveats are actually possible for
relkind=p partitions in v11. I assume those will never be implemented for
inheritence partitioning, so I propose another update to docs (if preferred,
I'll bring up on a new thread).
- unique constraints on parent table;
- FK constraints on parent table;
Note that FK constraints *referencing* a partitiond table are possible in v12
but not in v11. So if there's any finer-grained update to documentation of the
individual limitations, it'd need to be tweaked for back branches (v10 and 11).
