Cool. Unfortunately, I immediately ran into an obvious-in-retrospect
problem: the Homebrew libcurl we're linked against is not what you see
when you type `curl --version` at the command line, and I don't think
we record the runtime version of libcurl anywhere today. I've attached
a solution that should work well for PG20, but I don't feel as good
about it for 19 (or a backport to 18).

I need to switch to a different context for today, but tomorrow I'll
try to find a solution that touches only the test code.

Thanks,
