Description:

The syntax/synopsis of the "ALTER DEFAULT PRIVILEGES" statement on the
https://www.postgresql.org/docs/13/sql-alterdefaultprivileges.html page can
be simplified to the below form:
------------------------------------------------------------------------------------------
ALTER DEFAULT PRIVILEGES
    [ FOR { ROLE | USER } target_role [, ...] ]
    [ IN SCHEMA schema_name [, ...] ]
    abbreviated_grant_or_revoke

where abbreviated_grant_or_revoke is one of:

GRANT privileges TO { [ GROUP ] role_name | PUBLIC } [, ...] [ WITH GRANT
OPTION ]
REVOKE [ GRANT OPTION FOR ] privileges FROM { [ GROUP ] role_name | PUBLIC }
[, ...] [ CASCADE | RESTRICT ]

and privileges is one of:

{ { SELECT | INSERT | UPDATE | DELETE | TRUNCATE | REFERENCES | TRIGGER } [,
...] | ALL [ PRIVILEGES ] } ON TABLES
{ { USAGE | SELECT | UPDATE } [, ...] | ALL [ PRIVILEGES ] } ON SEQUENCES
{ EXECUTE | ALL [ PRIVILEGES ] } ON { FUNCTIONS | ROUTINES }
{ USAGE | ALL [ PRIVILEGES ] } ON TYPES
{ USAGE | CREATE | ALL [ PRIVILEGES ] } ON SCHEMAS
------------------------------------------------------------

This form is easier to understand.
