Обсуждение: some charts or graphs of possible permissions would be nice

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/11/sql-grant.html
Description:

Having read through the documentation on roles/granting I think I more or
less understand how it works, but what isn't really clarified is what the
overall universe of permissions that can be granted looks like. For example
I still didn't realize that to create a schema, you need to "GRANT CREATE"
to the role on the database before the role is allowed to do that. It's hard
to make a mental map of everything that a new role might need when I am
creating it.

That would be material for a tutorial rather than a documentation.

... but our documentation *does* have a tutorial, which could perhaps
gain a section about privileges.

What permissions issues do users typically struggle with? I personally 
have seen no problems in this area. Stephen sends one example; can you 
send more examples - or even a short text or a sketch of what you expect 
to be in the documentation?

More general: Is it a real problem? My experience is that in most cases 
permissions are handled at the application level, not at the database 
level. Is it worth to give more details? I don't think so. But it may be 
a good idea to follow Stephen's suggestion and put an introductory 
summary to the tutorial chapter.
