Fix psql describe commands' handling of ACL columns for old servers. Commit d1379ebf4 carelessly broke printACLColumn for pre-9.4 servers, by using the cardinality() function which we introduced in 9.4. We expect psql's describe-related commands to work back to 9.2, so this is bad. Use the longstanding array_length() function instead.
