Best practices for building and running on FreeBSD?

I'm looking for a document on best practices for building and
operating PostgreSQL on FreeBSD (amd64). Does such a thing already
exist? If not, I'm willing to put one together and maintain it.

Things I care about:
1) I need to run multiple postmasters on the same server. I think that
jails may provide a good way to virtualize this. I haven't seen any
documentation on running PostgreSQL in FreeBSD jails except for a
number of emails how it fails for FreeBSD 5.2.

2) Each of these postmasters may be running a different PostgreSQL
binary (or PostgreSQL binaries with different additional modules like
Slony1 included). The existing FreeBSD ports do not support having
multiple versions of the PostgreSQL binaries installed. Again, there
may be a work around for this using jails of which I am unaware.
Currently I'm contemplating simply building binary tarballs.

3) My sysadmin wants me to do the Right Thing with regards to
packaging.

4) I would strongly prefer to use DJB's services / multilog stuff to
handle logging the operation of the database.

5) I would like to conform to community standards with regards to
configure options to facilitate debugging or core dump analysis should
it be necessary.

Any guidance on this would be much appreciated.
