Thanks for the suggestion! I looked at these a bit, but they only work
if you have a known-ahead-of-time number of arguments. (I did explore
building an array and calling jsonb_build_object using VARIADIC, but you
can't build an array with alternating text & jsonb elements. That made
me curious how these functions even worked, which led me to
extract_variadic_args (utils/fmgr/funcapi.c), which has some magic to
support heterogeneous types when not called with the VARIADIC keyword,
so it seems they bypass the normal variadic handling.)
