I'd suggest avoiding creating the static cache variable
AuthenticatedUserIsReplicationRole. This can't possibly be sufficiently
interesting from a performance point of view to justify the risks
associated with stale cache values. Just look up the pg_authid syscache
entry when needed, ie, treat it more like rolcreaterole than rolsuper.
BTW, you forgot pg_dumpall support.
