Okay, I have done a round of more in-depth review, and the patch looks
to be in pretty good shape.

Relying on tuples_only to decide if the header should be printed or not
looks good to me.

+    /* check for value being non-empty and with an MB length of 1 */
+    if (*value == '\0' || value[PQmblen(value, pset.encoding)] != '\0')

It seems to me that this can just be replaced with that:
if (strlen(value) != 1)

Attached is what I am finishing up with for the moment.  Comments are
welcome.  I am still planning look at that stuff a bit more once again,
particularly the printing part, but I am lacking of time now..
