Cheers, nice to know it is possible... Now to see if i can get
java/python to do the same :) or to use a modified libpq somehow...

Does libpqtypes pass the array "over the wire" as an array? Ideally i'd like
to do this with jdbc, but might give me a pointer...
We send/receive the server's array format. This is not quite a C
array, and is definitely not a java array. It's a packed postgres
specific (network byte order) format. It is much faster and tighter
than text in some cases however. We present an interface to copy C
arrays to postgres style formats such as:
PGarray a;
PQgetf(res, tuple_num, "%int4[]", field_num, &a);
This will 'pop' a result out of your result that presents the array
internals (which you could then loop).
