Yeah. I'm also rather concerned about the bloat factor; it's
hardly unlikely that this line of development would double the
size of libpq, to add functionality that only a small minority
of applications would use. A client-side implementation also has
no choice but to cope with multiple server versions, and to
figure out what it's going to do about a too-new server.
Up to now we broke compatibility between libpq and server maybe
once every couple decades, but it'd be once a year for this.
