Examples

Run the following command to view the initial permissions of the new user role1:

select * from PG_DEFAULT_ACL;
 defaclrole | defaclnamespace | defaclobjtype |    defaclacl
------------+-----------------+---------------+-----------------
      16820 |           16822 | r             | {role1=r/user1}

You can also run the following statement to convert the format:

SELECT pg_catalog.pg_get_userbyid(d.defaclrole) AS "Granter",  n.nspname AS "Schema",  CASE d.defaclobjtype WHEN 'r' THEN 'table' WHEN 'S' THEN 'sequence' WHEN 'f' THEN 'function' WHEN 'T' THEN 'type' END AS "Type",  pg_catalog.array_to_string(d.defaclacl, E', ') AS "Access privileges" FROM pg_catalog.pg_default_acl d LEFT JOIN pg_catalog.pg_namespace n ON n.oid = d.defaclnamespace ORDER BY 1, 2, 3;

If the following information is displayed, user1 grants role1 the read permission on schema user1.

 Granter | Schema | Type  | Access privileges
---------+--------+-------+-------------------
 user1   | user1  | table | role1=r/user1
