Oh, actually it seems that :LAST_ERROR_MESSAGE is already just the
primary message, without any "at character N" addon, so this would be
a very easy way to ameliorate that complaint.  ("at character N" is
added by libpq's pqBuildErrorMessage3 in TERSE mode, but psql does
not use that when filling LAST_ERROR_MESSAGE.)
