Private namespace for libpqxx's internal use; do not access.
This namespace hides definitions internal to libpqxx. These are not supposed to be used by client programs, and they may change at any time without notice.
Conversely, if you find something in this namespace tremendously useful, by all means do lodge a request for its publication.
