Is it possible to construct my classes using libpqxx API and return it to client or I need to develop these API on another layer after data selection ? With the Pgfe C++ API (https://github.com/dmitigr/pgfe) it's possible to define any class and specialize the structure template Conversions to convert the data nicely from the database to this class and back.
