This is not needed. When a Postfix memcache is opened read-only,
the backup database is accessed in read-only mode, and it is accesed
only when information is not found in the cache.
Thus:
/etc/postfix/main.cf:
whatever = ... memcache:/etc/postfix/whatever ...
/etc/postfix/whatever:
backup = (pipeline or table)
should already work for read-only applications.
