Subject: Aggregates with internal state type?

Hi,
The PostgreSQL allows functions to define "internal" as parameter and
return types for functions, when those are not visible from SQL.
This lead me to the question whether it is possible to use "internal" as
state type for an Aggregate whose functions are implemented in C.
Thanks,
Markus
