> Do you see the binary transfers activating for array receives if you run your prepared statement select in a loop? That's the behaviour I see, athough something's setting my m_prepareThreshold to 5 rather than 3. I'm essentially using postgres as a persistent cache for my application server; when my app server starts it loads large amounts of data from postgres using a series of select-*-from-x queries. In order to minimise network I/O I'd ideally like a way to ensure I'm using the binary protocol from the very first query. Should I submit another patch that lets you configure this behaviour (either via a new JDBCUrl parameter or whether binaryTransfer is explicitly specified)?
Separately, do you know why this behaviour is the default? Is the binary encoding more expensive (either server-side or client-side) than text encoding the data?
