No, the "security_acl" also uses pg_security to translate between
security id (4bytes) and "aclitem[]" (variable length).
The Row-level ACLs facility internally translate the given acl array
into its own text representation, and stores it within pg_security.
We can use a common facility here to manage both of "acl" and "label".
