It exists because once upon a time when SRFs were first created, and you
were using a function returning SETOF RECORD, you would either have to
enumerate every column definition in your query, or create a "dummy"
table that had the right columns/types to match your return tuple.

That solution was generally viewed as grotty -- the former is a lot of
typing and clutter, and the latter creates a table with the only purpose
being to get the needed composite type created. Therefore we added the
ability to skip the table creation and just produce the needed composite
type.
