sql-createcast.html tells that
"It is normally not necessary to create casts between user-defined
types and the standard string types (text, varchar, and
char(n)). PostgreSQL will automatically handle a cast to a string
type by invoking the other type's output function, ..."
Therefore, this might help you:
test=# SELECT typoutput FROM pg_type WHERE typname = 'int4';
typoutput
-----------
int4out
(1 row)
