This option allows easy customization of certain initial database
properties, like encoding or collation. See:
https://www.postgresql.org/docs/9.5/app-initdb.html
Adding this option in already existing deployments will only cause
postgres pod restart, but no data loss or schema changes!
Intended to be used in further matrix deployment cleanups.

The way this was migrated is not to be spoken of.
(hint: it involved downtime, and mounting two volumes at once)
appservice-irc has some storage, we should migrate that to waw3, too. But
it's not as critical.
The new storage (waw3) is _much_ faster.
