Álvaro Herrera 412ef97d92 Fix error message for concurrent repack on materialized views ...

Previously, running REPACK (CONCURRENTLY) on a materialized view failed
with a confusing "has no identity index" error.

REPACK (CONCURRENTLY) replays changes decoded from WAL, but a
materialized view produces none, since it cannot be modified by DML and
REFRESH rewrites it through a transient heap that is not logically
decoded.

Fix this by reporting a clear error for materialized views upfront,
alongside the existing checks for system catalogs and TOAST tables, and
document the limitation.
