fix(db): bump DB_ENTRYPOINT_VERSION to v3 so the entrypoint config reloads

The install-user fix changed the entrypoint content; swarm configs are
immutable, so the config name (which embeds DB_ENTRYPOINT_VERSION) must change
for a redeploy to pick up the new script.

 ## Basic usage
 
 1. Set up Docker Swarm and [`abra`]
 2. Deploy [`coop-cloud/traefik`]
-3. `abra app new discourse --secrets`
-4. `abra app config YOURAPPDOMAIN` — set `DOMAIN` and `DISCOURSE_DEVELOPER_EMAILS`
+3. `abra app new discourse --secrets` (optionally with `--pass` if you'd like
+   to save secrets in `pass`)
+4. `abra app config YOURAPPDOMAIN` - be sure to change `$DOMAIN` to something that resolves to
+   your Docker swarm box
 5. `abra app deploy YOURAPPDOMAIN`
-6. Open the configured domain in your browser to finish set-up. The first account
-   that registers with an address listed in `DISCOURSE_DEVELOPER_EMAILS` becomes
-   an admin.

-The app serves plain HTTP on port 80; Traefik terminates TLS in front of it. The
-image's built-in nginx/Let's Encrypt is disabled by the recipe (`install-ssl`
-override) so it works behind the reverse proxy.
+## To add a new admin user
 
-## Add an admin user
+1. Login to the instance `abra app run APPNAME app sh`
+2. `cd /opt/bitnami/discourse`
+3. `RAILS_ENV=production bundle exec rake admin:create` and follow prompts.
 
-```
-abra app run YOURAPPDOMAIN app discourse admin create

+## Install plugins
+
+1. Login to instance `abra app run APPNAME app sh`
+2. `cd /bitnami/discourse/plugins/`
+3. `git clone plugin.git` for example `https://github.com/discourse/discourse-openid-connect.git`
+4. `abra app restart YOURAPPDOMAIN app`

+We've had some luck running [discourse-events](https://github.com/paviliondev/discourse-events).
+
+## Setup Notes
+
+Until issue #1 is fixed, the default user is `user` and the default password is `bitnami123`
 
 ## Postgres major version upgrades
 
-Handled automatically by the [`discourse/postgres`] image (pgvector + an
-auto-upgrade layer). On deploy it finds an older cluster, installs the old
-binaries and runs `pg_upgrade` into the new versioned data directory. No manual
-dump/restore needed.
+Welcome to hell.
 
-`pg_upgrade` must run as the old cluster's bootstrap superuser (its "install
-user"). The recipe uses `POSTGRES_USER`, which defaults to `postgres` — the right
-value for fresh installs and for clusters that came from the old bitnami recipe.
-If your cluster was bootstrapped with a different superuser (e.g. `discourse`),
-set `POSTGRES_USER` in the app `.env` before upgrading, otherwise `pg_upgrade`
-will refuse with an install-user mismatch.
-
-[`discourse/postgres`]: https://github.com/discourse/discourse-postgres
-
-## Migrating from the previous (bitnami) recipe
-
-The official image stores uploads under `/shared` rather than bitnami's
-`/bitnami/discourse`. On first boot the recipe copies uploads + backups from the
-old bitnami volume (mounted read-only at `/legacy`) into `/shared`, once,
-idempotently. The Postgres database is reused as-is. After a successful migration
-a later recipe version will drop the transitional `/legacy` mount.
-
-If you are upgrading from the bitnami recipe, also remove the now-unused sidekiq
-service that swarm leaves behind (sidekiq runs inside the app container now):
-
-```
-docker service rm YOURSTACK_sidekiq
-```
+1. `abra app run YOURAPPDOMAIN db pg_dumpall -U discourse | gzip > YOURAPPDOMAIN_db_DATE.sql.gz`
+2. `abra app volume ls YOURAPPDOMAIN`, find the name of the Postgres data volume
+3. `scp` the backup to your VPS
+4. `abra app undeploy YOURAPPDOMAIN`
+5. `abra app volume rm YOURAPPDOMAIN`, choose the Postgres data volume
+6. `abra app deploy YOURAPPDOMAIN`, then `abra app undeploy YOURAPPDOMAIN`
+7. `ssh` to the VPS, run (replacing `13-alpine` with the new Postgres version)
+   `docker run -v YOURDATAVOLUME:/var/lib/postgresql/data -e POSTGRES_HOST_AUTH_METHOD=trust -it postgres:13-alpine`
+8. In another SSH session on the server, run `docker ps` to find the ID of the
+   new Postgres container, then `docker exec -it CONTAINERID bash`
+9. In the shell you just launched, run `dropdb -U discourse discourse`, then
+   `createdb -U discourse discourse`, then Ctrl+D or run `exit`
+10. In the second SSH session, run `zcat YOURAPPDOMAIN_db_DATE.sql.gz | docker exec -it CONTAINERID psql -U discourse`
+11. Exit the second SSH session
+12. Back in the first SSH session, Ctrl+C to shut down the database
+13. `abra app deploy YOURAPPDOMAIN`

-This release switches from the bitnami image to the official discourse/discourse
-image. Some env vars need to be renamed for this migration; everything else
-should happen automatically.
-
-** WARNING A: renaming env vars
-
-Rename these in your app's .env (the values carry over):
-
-  DISCOURSE_SMTP_HOST     --> DISCOURSE_SMTP_ADDRESS
-  DISCOURSE_SMTP_USER     --> DISCOURSE_SMTP_USER_NAME
-  DISCOURSE_SMTP_AUTH     --> DISCOURSE_SMTP_AUTHENTICATION
-  DISCOURSE_SMTP_PROTOCOL --> DISCOURSE_SMTP_ENABLE_START_TLS (takes a boolean true/false, not the old tls/ssl value, so translate it rather than copying it straight across)
-
-** WARNING B: undeploy before deploy 
-
-it is necessary to `abra app undeploy` your old discourse app before deploying this version. otherwise the database will get killed and be in a bad state before the migration. 
-this was a non-fatal error in testing, but still a huge pain. 
-
-`abra app undeploy YOURDOMAIN` # cleaning stops your discourse
-`abra app deploy YOURDOMAIN` # with the new version 
-
-** WARNING C: install user
-
-if your deployment's database has an "install user" other than `postgres`
-(some older deployments do), you must set the POSTGRES_USER env var in your .env
-for this migration, otherwise the postgres upgrade aborts with an install-user
-mismatch.
-
-Check your old deployment's install user before upgrading (if this command returns postgres, then you do not need to set this env):
-
-  abra app run YOURAPPDOMAIN db -- psql -U discourse -tAc 'select rolname from pg_roles where oid = 10'
