These are tools to improve database design in particular situations.
Nobody really *needs* this, but then again, you don't really need CREATE
TYPE for composite types in the first place. Using CREATE TABLE instead
of CREATE TYPE creates a bunch of extra things you don't need. For
example, files are created, VACUUM and ANALYZE have to keep checking the
table, backup tools think they have to back up the table, and you have
to check that no one actually inserts anything into the table.

This is part of the SQL standard.
