After trying out a few different EPUB readers on iOS (iPhone), I think this is simply a quality-of-implementation issue with iBooks.

Its page counting is much more nonsensical, but that just seems to support my earlier theory. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
