Actually, wouldn't a table-level property be completely inappropriate for
that? Imagine one publication that's used for HA (or major version upgrade)
and doesn't use a conflict table, which replicates all tables (including the
conflict table of another pub/sub). And a subscription doing bi-direction
replication that *does* obviously use the conflict table. In one of those
cases you want to replicate changes to the conflict table, in the other
not. So a table / pg_class property would be inappropriate, no?
