I disagree.  I think PQinitSSL is meant to be called from the
application, for example.  Same with PQsetClientEncoding.  And the
PQExpBuffer stuff is all very useful, and years ago when I wrote an app
to use it it annoyed me that there were no docs on it.  (Back then, I
didn't realize I could have complained about it or written the docs
myself).
