I do agree tha thaving both would be useful. We could have something like
int PQgetSSLstruct(void **sslstruct)

which returns the type of struct. Then it's up to the application to
know if it can handle it. For those apps that need a *lot*. But the
basic attributes - something like the list from apache - should be
retrievable in a library independent way.
