Tom Lane 1591b38d17 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.

Per report from Christoph Berg.  Back-patch to v17.
