Block ALTER TABLE .. DROP NOT NULL on columns in replica identity index
Replica identities that depend directly on an index rely on a set of
properties, one of them being that all the columns defined in this index
have to be marked as NOT NULL. There was a hole in the logic with ALTER
TABLE DROP NOT NULL, where it was possible to remove the NOT NULL
property of a column part of an index used as replica identity, so block
it to avoid problems with logical decoding down the road.
The same check was already done columns part of a primary key, so the
fix is straight-forward.
