I tried a few:
chcon -t postgresql_db_t /home/pgsql
type things. No luck.
It's interesting that there are no permission denials
logged in /var/log/messages, but postgresql
says it can't access /var/lib/pgsql/data/base
because permission is denied (in the postgres log).
I played with the symlink chcon user, and the /home/pgsql user
as well (again, chcon, not chown).
It's clearly selinux though. If I do this:
/usr/sbin/setenforce 0
Then everything works peachy for my testing.
But turning off selinux is probably a one way road,
since all files created in that environment won't have their
context set. So I really need to solve this in the correct fashion.
For now I'll run with the database files under /var/lib/pgsql/data
until I (or someone else) can figure out the selinux/postgresql magic.
