Huh?
postgres=# \df round
List of functions
Schema | Name | Result data type | Argument data types | Type
------------+-------+------------------+---------------------+------
pg_catalog | round | double precision | double precision | func
pg_catalog | round | numeric | numeric | func
pg_catalog | round | numeric | numeric, integer | func
(3 rows)
The description in the docs matches reality AFAICS.
