avoid using const_cast, new release 2.3.2 * pq_connection.h/cc: octave_pq_connection now contains pointer to object of new class octave_pq_connection_rep, containing the pq-specific members formerly in octave_pq_connection. * pq_exec.cc, pq_close.cc, pq_update_types.cc, pq_conninfo.cc, pq_lo.cc: Remove const_cast, use octave_pq_connection_rep object instead. * __pq_connect__.cc, converters.h/cc, converters_arr_comp.cc, command.h/cc: Use octave_pq_connection_rep instead of octave_pq_connection.
