Michael Paquier fc95d35b94 Correct comment and some documentation about REPLICA_IDENTITY_INDEX
catalog/pg_class.h was stating that REPLICA_IDENTITY_INDEX with a
dropped index is equivalent to REPLICA_IDENTITY_DEFAULT.  The code tells
a different story, as it is equivalent to REPLICA_IDENTITY_NOTHING.

The behavior exists since the introduction of replica identities, and
fe7fd4e even added tests for this case but I somewhat forgot to fix this
comment.

While on it, this commit reorganizes the documentation about replica
identities on the ALTER TABLE page, and a note is added about the case
of dropped indexes with REPLICA_IDENTITY_INDEX.
