The basic process is this:
initdb your database (I assume you've already done that.)
shut down the database
as the pg user, cd to $PGDATA
cp -Rfp pg_xlog /some/other/vol/pg_xlog/
mv pg_xlog pg_xlog_old
ln -s /some/other/vol/pg_xlog pg_xlog
restart database.
Note that you want the other directory set to the proper permissions
(0700) and ownership (your pg user).
