I have contemplated a maintenance script that would track either the
md5 checksums of the /usr/lib/locale/*/LC_COLLATE files or the version
of installed locale packages and automatically reindex things when
they change (I guess after restarting the cluster to clear any glibc
caches that might be lurking in long running backends).  Or at least
tell me that's needed.  Obviously completely OS-specific...
