I'd Like To See Permissions Granted

I'm just getting started using PostgreSQL and I was successfully able to create a table.  I'd like to be able to look
atwhat pemissions I've granted and see in the documentation that there is a view called usage_privileges but when I
attemptto look at this table (i.e., select * from usage_privileges) I get, 'ERROR:  relation "usage_privileges" does
notexist'.  What do I need to do in order to look at the contents of this view?
