As I said, I did not (yet) test the V3 stuff. V2/V3 does indeed refer to the protocol level. From a technical standpoint the V3 is better, more efficient. On the other hand, PostgresV2 is good enough and has seen lots of usage. PostgresV3 is a bit strange in that respect: it exists and is OS, but there is nobody pushing it... > On Mon, Mar 3, 2014 at 8:25 AM, Sven Van Caekenberghe <[email protected]> wrote: > Doru, > > Note that there is also the newer > > http://www.squeaksource.com/PostgresV3.html > > which implements a more recent, incompatible version of the wire protocol > between the client and server.
