I was reading the partitioning docs when I spotted this. I think it means to
highlight the advantages of DROP TABLE over DELETE rather than ALTER TABLE.

Bulk loads and deletes can be accomplished by adding or removing
partitions, if that requirement is planned into the partitioning design.
! <command>ALTER TABLE</> is far faster than a bulk operation.
It also entirely avoids the <command>VACUUM</command>
overhead caused by a bulk <command>DELETE</>.
