Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# PG\$1DEFAULT\$1ACL
PG\$1DEFAULT\$1ACL

Stores information about default access privileges. For more information on default access privileges, see [ALTER DEFAULT PRIVILEGES](r_ALTER_DEFAULT_PRIVILEGES.md).

PG\$1DEFAULT\$1ACL is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see [Visibility of data in system tables and views](cm_chap_system-tables.md#c_visibility-of-data).

## Example
Example

The following query returns all default privileges defined for the database. 

```
select pg_get_userbyid(d.defacluser) as user, 
n.nspname as schema, 
case d.defaclobjtype when 'r' then 'tables' when 'f' then 'functions' end 
as object_type, 
array_to_string(d.defaclacl, ' + ')  as default_privileges 
from pg_catalog.pg_default_acl d 
left join pg_catalog.pg_namespace n on n.oid = d.defaclnamespace;

 user  | schema | object_type |              default_privileges
-------+--------+-------------+-------------------------------------------------------
 admin | tickit | tables      | user1=r/admin + "group group1=a/admin" + user2=w/admin
```

The result in the preceding example shows that for all new tables created by user `admin` in the `tickit` schema, `admin` grants SELECT privileges to `user1`, INSERT privileges to `group1`, and UPDATE privileges to `user2`.
