how about a test for the thing like:
printf("%2$s %1$s!\n", "world", "Hello");
It is what I am trying to solve :(

src/port/snprintf.c is not not a particularly pretty. And
after my rework it got even uglier. I have looked at
FreeBDS's one and it is not *that* complicated. Would
you like me to try to incorporate into PostgreSQL.
NetBSD's one is somewhat simplier but does not
support %n$ feature by the way.
