There was some talk, either on this list or freebsd-performance about
setting the default block size for PostgreSQL running on FreeBSD to be 16k
because of performance reasons. That is: *default* for the port, user is not

needed thing.

Depends on what you consider 'unusual'? I hope not things like iso8859-x
(or, to be exact, European languages) :)
