Thread: libpqtypes - libpqtypes: Update PQparamCreate and PQregisterTypeHandler

Log Message:
-----------
Update PQparamCreate and PQregisterTypeHandler man pages to include a warning about what types will be available to a
PGparam. Obviously, you must first register a type before you can use it.  But, it is better to document this to avoid
confusion.
