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

I know this post is old but I made another query based on the different answers to have one that is short and easy to use afterward :

select
    nspname as schema_name
    , r.rolname as role_name
    , pg_catalog.has_schema_privilege(r.rolname, nspname, 'CREATE') as create_grant
    , pg_catalog.has_schema_privilege(r.rolname, nspname, 'USAGE') as usage_grant
from pg_namespace pn,pg_catalog.pg_roles r
where array_to_string(nspacl,',') like '%'||r.rolname||'%' 
    and nspowner > 1 

I keep thinking one day I will make a query to have all rights in only one view... One day. ;)
