Yeah, an explicit syntax is better.
I've researched other syntax, but I cannot find any good ones.

* ALTER TABLE child INHERIT parent AS PARTITION
=> implemenation "PARTITION is an INHERIT" is revealed to user.
* ALTER PARTITION child ATTACH TO parent
=> child is not a partition yet at that point.
* ALTER TABLE parent ADD PARTITION child
=> "partition" need to be a full-reserved word.

Are there better idea?
