You need libpqtypes (client-side library). It requires a new 8.4
feature called libpq-events, but there is an 8.3 patch available. If
you willing to patch your 8.3.5 libpq client, than this should meet your
needs.

Documentation: http://libpqtypes.esilo.com/
For arrays, libpqtypes gives you a PGresult where each tuple is an array
item. For composite arrays, each composite field is a PGresult field.

That is true. Our testing has proven this. It also reduces the overall
coding effort.
