Restrict REPACK (CONCURRENTLY) on user catalog tables. REPACK (CONCURRENTLY) is not an MVCC-safe operation; it doesn't preserve the visibility information, which logical decoding needs because it reads user catalog tables under a historic snapshot. Disallow REPACK (CONCURRENTLY) on user catalog tables. Removing this check requires making it MVCC-safe and logical rewrite mappings. Backpatch to v19, where REPACK (CONCURRENTLY) was introduced.
