Those are OIDs from the pg_type catalog. The format_type(oid, integer)
function can give you the actual name, as in
alvherre=# SELECT proacl, proargtypes, format_type(proargtypes[0], 0),
format_type(proargtypes[1], 0) FROM pg_proc WHERE proname='to_ascii';
proacl | proargtypes | format_type | format_type
---------------+-------------+-------------+-------------
{=X/alvherre} | 25 | text | -
{=X/alvherre} | 25 19 | text | name
{=X/alvherre} | 25 23 | text | integer
(3 filas)
The second argument is the type's typmod (the 25 in varchar(25), for
instance).
