I finally took enough time to actually understand (I think) your
proposal. The key point seems to be around ALTER ROLE SET and such like
dynamic setting of a local_preload_libraries.

Would it make sense to review the local_preload_libraries semantics
instead? It looks like session_preload_libraries only adds flexibility,
and that current usages of local_preload_libraries would be served as
well by the new setting.

Did you figure out a case where a local_preload_libraries setting would
stop working if made into a session_preload_libraries setting?
