It appears that neither of us actually tested that this works. For me,
it works when I test as a superuser, but if I test as a non-superuser
with or without pg_write_server_files, it crashes, because we end up
trying to do syscache lookups without a transaction environment. I
*think* that the attached is a sufficient fix; at least, it passes
simple testing.
