Commit 28d534e2ae introduced reform_tuple() with a fast path that
returns the source tuple verbatim when no dropped columns require fixing
up. I (Álvaro) failed to realize that this broke handling of columns
with a 'missingval' defined: after a VACUUM FULL, CLUSTER, or REPACK
operation, the catalogued missingval is thrown away, so the tuples are
no longer correct.
Fix by forcing the rewrite when the tuple is shorter than the tuple
descriptor.
