55b0aa847a Fix GHSA-3h7q-rfh9-xm4v
Weakness in auth chain indexing allows DoS from remote room members
through disk fill and high CPU usage.

A remote Matrix user with malicious intent, sharing a room with Synapse
instances before 1.104.1, can dispatch specially crafted events to
exploit a weakness in how the auth chain cover index is calculated. This
can induce high CPU consumption and accumulate excessive data in the
database of such instances, resulting in a denial of service.

Servers in private federations, or those that do not federate, are not
affected.

Correctly mention previous copyright (#16820)
During the migration the automated script to update the copyright

Reinstate them.

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.

Remove the last reference to event_txn_id. (#16521)
This table was no longer used, except for a background process
which purged old entries in it.

Mark sync as limited if there is a gap in the timeline (#16485)
This splits thinsg into two queries, but most of the time we won't have
new event backwards extremities so this shouldn't actually add an extra
RTT for the majority of cases.

Note this removes the check for events with no prev events, but that was
part of MSC2716 work that has since been removed.
