temp-config can only be used when bootstrapping a temporary environment, so
when using e.g. make check. PGXS / third-party extension can only use
installcheck, so if you need specific config like shared_preload_libraries you
need to manually configure your instance beforehand, or indeed rely on TAP
tests. Most projects properly setup their instance in the CI jobs, and at
least the Debian packaging infrastructure has a way to configure it too.
