What puzzled me is starting postgresql failed at boot

(Maybe different contexts are applied to the logged-in root
and the init program?)
Running the initscript should be exactly the same as the boot
process. Starting the service manually (without the initscript)
would be different though, as no domain transition would happen.
Both
service postgresql start
and
su - postgres
PGDATA=/home1/pgsql pg_ctl start
started successfully if I logged in as root or under "su -" from my
mortal uid.
(The postgresql initscript uses "runuser" instead of "su" IIRC.)
Do the AVCs logged during the boot process show the process running
as postgresql_t? If you do a "ps uaxZ", is it running as
postgresql_t or unconfined_t?
It's running under postgresql_t.
Does it run under postgresql_t if you start it using pg_ctl?

# service postgresql stop
# su - postgres

That one's as I expected.

Both times it's running under unconfined_t, so it doesn't matter
whether it's running under "su - postgres" or "runuser - postgres".
It seems what matters is that it's started from a logged in user:
I'd have expected this to run as postgresql_t
Is your postgresql initscript correctly labelled as initrc_exec_t?
What's the state of the postgresql_disable_trans boolean?
# getsebool postgresql_disable_trans
