No, I roll my own BEs, using:

roughly, you will want to do:
take backup (pg_dump)
add the new user to the database
fix the pg_hba.conf to have the new user
restart pg
alter default user to new user
shutdown pg
remove pgsql entries from pg_hba.conf
add postgres user to freebsd. use same UID so you don=E2=80=99t need to =
chown anything
upgrade postgres
start pg
you should now have pg running as new (unix) user, and you should be =
able to connect as the new user
delete pgsql user (nolonger needed or used)
