[Libpqxx-general] Retrieving data from large integers fields

[João Pedro Alves P. do Nascimento]

Jeroen,

Ok, followed your recommendation and that did the trick. Also in the first
place, my program was trying to use another version of the pqxxd.dll which
wasn't compiled with the PQXX_HAVE_LONG_LONG (my mistake).

Thank you very much for your help,

Joao Pedro
