postgresql - view schema privileges

Question

Is there a query I can run to show currently assigned privileges on a particular schema?

i.e. privileges that were assigned like so:

GRANT USAGE ON S         


        

Answer 1

This is what psql uses internally :)

SELECT n.nspname AS "Name",
  pg_catalog.pg_get_userbyid(n.nspowner) AS "Owner",
  pg_catalog.array_to_string(n.nspacl, E'\n') AS "Access privileges",
  pg_catalog.obj_description(n.oid, 'pg_namespace') AS "Description"
FROM pg_catalog.pg_namespace n
WHERE n.nspname !~ '^pg_' AND n.nspname <> 'information_schema'
ORDER BY 1;
