Really?  What aspect of postgis requires mucking with
shared_preload_libraries?

If you ask me, shared_preload_libraries was only ever meant as a
performance optimization.  If user-visible DDL behavior depends on a
library being preloaded that way, that feature is broken.  There
are some cases where we probably don't care enough to provide a
proper solution, but I'm not sure why we would think that security
labels fall in the don't-really-give-a-damn-if-it-works class.
