Add a Postgres REPLICA IDENTITY to tables that do not have an implicit one. This should allow use of Postgres logical replication. (take 2, now with no added deadlocks!) (#16658)

* Add `ALTER TABLE ... REPLICA IDENTITY ...` for individual tables

We can't combine them into one file as it makes it likely to hit a deadlock

if Synapse is running, as it only takes one other transaction to access two

tables in a different order to the schema delta.

* Add notes

* Newsfile

+The `10_replica_identity_xxx.sql.postgres` series of schema deltas adds replica identities for tables that do not have one implicitly as a result of having a primary key.
+
+This is needed to use logical replication with Synapse (at least without `UPDATE` and `DELETE` statements failing!).
+
+Where possible, we use an existing `UNIQUE` index on `NOT NULL` columns as the replica identity. Otherwise, we have to fall back to using the full row as a replica identity.
+
+Unfortunately, by running all the `ALTER TABLE` statements in one schema delta per database, it was too likely to hit a deadlock as it would only take
+one other transaction from a running Synapse worker to access the tables out of order and trigger a deadlock.
+
+By having each statement in its own delta file, each one is run in its own transaction and only needs to take a very brief (instant) lock on the table but no other tables,
+so there should be no chance of deadlock.
+
+Like many schema deltas we already apply to Synapse, it is probably blocked by an ongoing `pg_dump`.
