This technique works equally for external functions which return deferreds,
or deferreds we have made ourselves.
XXX: think this is what ``preserve_context_over_deferred`` is supposed to do,
though it is broken, in that it only restores the logcontext for the duration
of the callbacks, which doesn't comply with the logcontext rules.
You can also use ``logcontext.make_deferred_yieldable``, which just does the
boilerplate for you, so the above could be written:
.. code:: python
def sleep(seconds):
return logcontext.make_deferred_yieldable(get_sleep_deferred(seconds))

Once that has completed, change the synapse config to point at the PostgreSQL
database configuration file using the ``database_config`` parameter (see
`Synapse Config`_) and restart synapse. Synapse should now be running against
database configuration file ``homeserver-postgres.yaml`` (i.e. rename it to
``homeserver.yaml``) and restart synapse. Synapse should now be running against

work reliably for guests. However, it does introduce a security risk
as it lets guests connect to arbitrary endpoints without having gone
through a CAPTCHA or similar to register a real account.
