The following review has been posted through the commitfest application:
make installcheck-world: tested, passed
Implements feature: tested, passed
Spec compliant: tested, passed
Documentation: not tested
I tested the patch on the master branch (addd034) and it works fine.
I think that test case which non-superuser can't see this parameter is unnecessary.
There is a similar test for pg_read_all_settings role.
The new status of this patch is: Ready for Committer
