While the previous commit handles the common case of all of the server
being started already, it still produces ERROR output lines from
supervisorctl when most of the server is already running. Take the
case where one worker is stopped:
```
$ supervisorctl stop zulip-workers:zulip_events_deferred_work
zulip-workers:zulip_events_deferred_work: stopped

```
More gracefully handle these cases:
```

```
Currently, the output from `start-server` if the server is already
running is potentially confusing, since it says ERROR several times:
```
$ ./scripts/start-server
2023-04-04 15:35:12,737 start-server: Running syntax and database checks
System check identified no issues (15 silenced).
2023-04-04 15:35:16,211 start-server: Starting Tornado process on port 9800

2023-04-04 15:35:16,844 start-server: Starting django server

zulip_deliver_scheduled_messages: ERROR (already started)
process-fts-updates: ERROR (already started)
2023-04-04 15:35:18,923 start-server: Done!
```
Catch the simple common case where all of the services are already
running, and output a clearer success message:
```
$ ./scripts/start-server
2023-04-04 15:39:52,367 start-server: Running syntax and database checks
System check identified no issues (15 silenced).
2023-04-04 15:39:55,857 start-server: Zulip is already started; nothing to do!
```
Primary goal of library replacement is improving execution speed.

Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.

These hooks are run immediately around the critical section of the
upgrade. If the upgrade fails for preparatory reasons, the pre-deploy
hook may not be run; if it fails during the upgrade, the post-deploy
hook will not be run. Hooks are called from the CWD of the new
deploy, with arguments of the old version and the new version. If
they exit with non-0 exit code, the deploy aborts.
Corepack manages multiple per-project version of Yarn and PNPM, which
means we have to maintain less installation code, and could help us
switch away from Yarn 1 without making the system unusable for
development of other Yarn 1 projects.

Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.

The `pg_upgrade` tool uses `pg_dump` as an internal step, and verifies
that the version of `pg_upgrade` is the same exactly the same as the
version of the PostgreSQL server it is upgrading to. A mismatch (even
in packaging versions) leads to it aborting:
```
/usr/lib/postgresql/14/bin/pg_upgrade -b /usr/lib/postgresql/13/bin -B /usr/lib/postgresql/14/bin -p 5432 -P 5435 -d /etc/postgresql/13/main -D /etc/postgresql/14/main --link

```
Explicitly upgrade `postgresql-client` at the same time we upgrade
`postgresql` itself, so their versions match.

This was last really used in d7a3570c7e, in 2013, when it was
`/home/humbug/logs`.
Repoint the one obscure piece of tooling that writes there, and remove
the places that created it.
`check_version` in `install-yarn` had the rather careful check that
the yarn it installed into `/usr/bin/yarn` was the yarn which was
first in the user's `$PATH`. This caused problems when the user had a
pre-existing `/usr/local/bin/yarn`; however, those problems are
limited to the `install-yarn` script itself, since the nearly all
calls to yarn from Zulip's code already hardcode the `/srv/zulip-yarn`
location, and do not depend on what is in `$PATH`.
Remove the checks in `install-yarn` that depend on the local `$PATH`,
and stop installing our `yarn` into it. We also adjust the two
callsites which did not specify the full path to `yarn`, so use
`/srv/zulip-yarn`.

During installation on a new host, `create-database` attempts to
verify that there isn't a bunch of data already in the database which
is it about to drop and recreate. In the most common case, this
statement emits a scary-looking warning, since the database does not
exist yet:
```
+ /home/zulip/deployments/current/scripts/setup/create-database
+ POSTGRES_USER=postgres
++ crudini --get /etc/zulip/zulip.conf postgresql database_name
++ echo zulip
+ DATABASE_NAME=zulip
++ crudini --get /etc/zulip/zulip.conf postgresql database_user
++ echo zulip
+ DATABASE_USER=zulip
++ cd /
++ su postgres -c 'psql -v ON_ERROR_STOP=1 -Atc '\''SELECT COUNT(*) FROM zulip.zerver_message;'\'' zulip'
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: database "zulip" does not exist
```
Because we are attempting to gracefully handle the case where the
database does not exist yet, we also continue (and drop the database)
in other, less expected cases -- for instance, if database contains a
schema we do not expect.
Explicitly check for the database existence first, and once we verify
that, allow any further failures in the `SELECT COUNT(*)` to abort
`create-database`. This serves the dual purpose of hiding the "FATAL"
error for the common case when the database does not exist, as well as
preventing dropping the database if anything else goes awry.
If a previous attempt at an upgrade failed for some reason, the new
PostgreSQL may be installed, and the conversion will succeed, but the
new PostgreSQL daemon will not be running (Puppet does not force it to
start). This causes the upgrade to fail when analyzing statistics,
since the daemon isn't running.
Explicitly start the new PostgreSQL; this does nothing in most cases,
but will provider better resiliency when recovering from previous
partial upgrades.
Some terminals (e.g. ssh from OS X) set an invalid locale, which
causes the `pg_upgradecluster` call late in the upgrade to fail.
Force a known locale, for consistency. This mirrors the settings in
upgrade-zulip-stage-2, set in 11ab545f3b, and its subsequent
cleanups in 64c608a51a, ee0f4ca330, and eda9ce2364.
‘exit’ is pulled in for the interactive interpreter as a side effect
of the site module; this can be disabled with python -S and shouldn’t
be relied on.
Also, use the NoReturn type where appropriate.

Starting with wal-g 2.0.1, they provide `aarch64` assets[^1].
Effectively revert d7b59c86ce, and use
the pre-built binary for `aarch64` rather than spend a bunch of space
and time having to build it from source.
