* 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.

poetry-core 1.8.x includes a fix which properly moves the generate
synapse_rust.abi3.so file to the synapse directory when using an
editable install.
Without this change developers are left with a confusing experience
of the synapse.synapse_rust module not being found after installation.
Implement MSC3860 to follow redirects for federated media downloads.
Note that the Client-Server API doesn't support this (yet) since the media
repository in Synapse doesn't have a way of supporting redirects.
* Describe `insert_client_ip`
* Pull out client_ips and MAU tracking to BaseAuth
* Define HAS_AUTHLIB once in tests
sick of copypasting
* Track ips and token usage when delegating auth
* Test that we track MAU and user_ips
* Don't track `__oidc_admin`
Keeping track of a lower bound of stream ID where we've deleted everything below makes the queries much faster. Otherwise, every time we scan for rows to delete we'd re-scan across all the rows that have previously deleted (until the next table VACUUM).
If a worker reconnects to Redis we send out the current positions of all our streams. However, if we're also trying to send out a backlog of RDATA at the same time then we can end up sending a `POSITION` with the current token *before* we've sent all the RDATA before the current token.
This doesn't cause actual bugs as the receiving servers see the POSITION, fetch the relevant rows from the DB, and then ignore the old RDATA as they come in. However, this is inefficient so it'd be better if we didn't send out-of-order positions

If simple_{insert,upsert,update}_many_txn is called without any data
to modify then return instead of executing the query.
This matches the behavior of simple_{select,delete}_many_txn.
Fetch information needed for push rule evaluation in parallel.
Ideally this would use query pipelining, but this is not
available in psycopg2.
Due to the database thread pool this may result in little
to no parallelization.
Previously only Twisted's EPollReactor was compatible with the
reactor timing metric, notably not working when asyncio was used.
After this change, the following configurations support the reactor
timing metric:
* poll, epoll, or select reactors
* asyncio reactor with a poll, epoll, select, /dev/poll, or kqueue event loop.
The event persistence code used to handle multiple rooms
at a time, but was simplified to only ever be called with a
single room at a time (different rooms are now handled in
parallel). The code is still generic to multiple rooms causing
a lot of work that is unnecessary (e.g. unnecessary loops, and
partitioning data by room).
This strips out the ability to handle multiple rooms at once, greatly
simplifying the code.
Just to standardize on the normal helpers, it might also have
a slight perf improvement on PostgreSQL which will now use
`ANY (?)` instead of `IN (?, ?, ...)`.
* complement: enable dirty runs
* Add changelog
* Set a low connpool limit when running in Complement
Dirty runs can cause many containers to be running concurrently,
which seems to easily exhaust resources on the host. The increased
speedup from dirty runs also seems to use more db connections on
workers, which are misconfigured currently to have
`SUM(workers * cp_max) > max_connections`, causing
```
FATAL: sorry, too many clients already
```
which results in tests failing.
* Try p=2 concurrency to restrict slowness of servers which causes partial state join tests to flake
* Debug logging
* Only run flakey tests
* Only adjust connection pool limits in worker mode
* Move cp vars to somewhere where they get executed in CI
* Move cp values back to where they actually work
* Debug logging
* Try p=1 to see if this makes worker mode happier
* Remove debug logging
This is mostly useful for federated rooms where some users
would get stuck in the invite or knock state when the room
was purged from their homeserver.
This adds a module API which allows a module to update a user's
presence state/status message. This is useful for controlling presence
from an external system.
To fully control presence from the module the presence.enabled config
parameter gains a new state of "untracked" which disables internal tracking
of presence changes via user actions, etc. Only updates from the module will
be persisted and sent down sync properly).
