From cb7fb3ca958ec8bd5a14e740c067f1d096af3454 Mon Sep 17 00:00:00 2001

Subject: First phase of FE/BE protocol modifications: new StartupPacket layout
 with variable-width fields.  No more truncation of long user names. Also,
 libpq can now send its environment-variable-driven SET commands as part of
 the startup packet, saving round trips to server.
