How do I view grants on Redshift

Question

I\'d like to view grants on redshifts.

I found this view for postgres:

CREATE OR REPLACE VIEW view_all_grants AS 
SELECT 
  use.usename as subject, 
         


        

Answer 1

Here is another useful query to view grants on schema (usage, create) by user that I created based on the query above by @drtf:

SELECT * 
FROM 
    (
    SELECT 
        schemaname
        ,usename
        ,HAS_SCHEMA_PRIVILEGE(usrs.usename, schemaname, 'usage') AS usg
        ,HAS_SCHEMA_PRIVILEGE(usrs.usename, schemaname, 'create') AS crt
    FROM
        (
        SELECT distinct(schemaname) FROM pg_tables
        WHERE schemaname not in ('pg_internal')
        UNION
        SELECT distinct(schemaname) FROM pg_views
        WHERE schemaname not in ('pg_internal')
        ) AS objs
        ,(SELECT * FROM pg_user) AS usrs
    ORDER BY schemaname
    )
WHERE (usg = true or crt = true)
--and schemaname=''
--and usename = '';
