Strange timing since I was just testing this. Here's what I got:

$ pg/bin/psql -h localhost -U vagrant(at)PGMASTERS(dot)NET postgres
conn->inStart = 179, conn->inEnd = 179, conn->inCursor = 179
psql (9.6devel)
Type "help" for help.

postgres=>

This was after commenting out:

// appendBinaryPQExpBuffer(&conn->gwritebuf,
// conn->inBuffer + conn->inStart,
// conn->inEnd - conn->inStart);
// conn->inEnd = conn->inStart;

The good news I can log on every time now!
