I don't disagree with that, but surely checking if it's the same OID and
exiting immediately is going to be faster than comparing the policy
names.
Now, looking at the code, I'm actually failing to see a case where we
use the RowSecurityPolicy->policy_name.. Perhaps *that's* what we
should be looking to remove?
Thanks!
