No need to be the pguser user at all. Any user of the system can run a postgres
cluster. Note, that is a postgres cluster, i.e. if you're trying to start
postgres to look at databases in a cluster that was built by a different user
then it isn't going to work.

So in summary, what you want to do is something like:

initdb -D /home/myuser/data blah blah blah
pg_ctl -D /home/myuser/data blah blah blah
createdb -D /home/myuser/data blah blah blah
all the other stuff to build your DBs and then you just need to fork and exec
as myuser in your application.
