I am just guessing here, not having done the experiment --- but I'm not
at all sure that that will let you escape the SELinux policy
restrictions. I suspect you will find that you have no choice but to
alter the policy to allow the postgres daemon to access your nondefault
data area. (Or turn off SELinux, but that might be an overreaction.)
It might be possible to make an end-run by using a nondefault
installation of Postgres --- if the postmaster executable doesn't live
in /usr/bin, I *think* (but am not certain) that the SELinux targeted
policy will not think it's supposed to constrain the daemon's actions.
Then you are back to relying solely on filesystem permissions; but that
seems like plenty to me.
