Fetch many records at time in iter() on named cursors
Reported by Daniele Varrazzo | January 13th, 2011 @ 04:10 PM
Using named cursor, records are fetched one at time, with a lot of network roundtrips. A more efficient way of fetching data is using fetchmany.
There may be a default number of record to be fetched internally to make iteration more efficient.
