Well, it is a one-to-one conversion. A float8 == double precision. They
are mapped together very early. Similarly for integer == int4. If you
look in the pg_type table, you'll see there are no entries for
"integer" or "double precision".
The fancy output is mostly for compatability purposes (SQL defines
these names).
Have a nice day,
