AFAIK, DBD:Pg never uses a cursor unless you ask it to. So you probably
want to code a loop like:
DECLARE CURSOR blah AS ...
while( FETCH 1000 )
{
process rows...
}
If you don't use a cursor in the backend, then DBI will try to pull the
*entire* result and store it in memory, which is why you don't have
enough...
Hope this helps,
