pgsql: Add documentation: >>>I think a more accurate description would

Log Message:

Add documentation:

>>>I think a more accurate description would be "permissions not
>>>inherited by children," and that isn't necessarily a bug.
>>
>>I agree it may not be a bug - but it's more than the permissions not
>>being inherited: the parent is affected.
>

> Not really, once you understand what's happening.  Unless you use

> its children.  The parent itself isn't affected, as queries with
> FROM ONLY should demonstrate.  I understand what you're saying --
> that there's an apparent effect on the parent -- but there really
> isn't.
