It would be nice, and I briefly looked into removing the "first"
requirement, but src/backend/tcop/postgres.c for one assumes that --single
is always argv[1], and it seemed not worth the extra effort to make it work
for argv[N] instead of argv[1]. I don't mind it being the first argument,
but that confusing error message needs to go.
