[GENERAL] What's the benefit (or usage scenario) of a "typed table"? - Mailing list pgsql-general

I recently stumbled over "typed tables" in Postgres
(there were several questions containing this on stackoverflow recently)

     create type some_type as (id integer, data text);
     create table some_table of some_type;

I wonder what the benefit of a typed table is and when this would be useful?
