notplants 9f61774737 fix(db): switch postgres image to pgvector/pgvector:pg17 + bump PG_BACKUP_VERSION

- Switch db image from postgres:16 to pgvector/pgvector:pg17. The
  bundled discourse-ai plugin's migration 20230710171141 runs
  'CREATE EXTENSION IF NOT EXISTS vector' on every boot; without
  the extension binaries installed in the postgres image, the
  migration transaction is aborted and the app crash-loops. The
  pgvector image is debian-based (bookworm) with the postgres
  apt repo + pgdg.list already configured, so the recipe's
  homegrown pg_upgrade entrypoint continues to work across major
  version bumps.
- Bump PG_BACKUP_VERSION v1 → v2: the prior 'improved comments'
  commit edited pg_backup.sh content without bumping the config
  version, so any operator redeploying without a fresh stack
  would hit 'only updates to Labels are allowed' from docker
  swarm (configs are immutable; content change needs a new name).

Postgres major version upgrades

Welcome to hell.

abra app run YOURAPPDOMAIN db pg_dumpall -U discourse | gzip > YOURAPPDOMAIN_db_DATE.sql.gz
abra app volume ls YOURAPPDOMAIN, find the name of the Postgres data volume
scp the backup to your VPS
abra app undeploy YOURAPPDOMAIN
abra app volume rm YOURAPPDOMAIN, choose the Postgres data volume
abra app deploy YOURAPPDOMAIN, then abra app undeploy YOURAPPDOMAIN
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
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
In the shell you just launched, run dropdb -U discourse discourse, then createdb -U discourse discourse, then Ctrl+D or run exit
In the second SSH session, run zcat YOURAPPDOMAIN_db_DATE.sql.gz | docker exec -it CONTAINERID psql -U discourse
Exit the second SSH session
Back in the first SSH session, Ctrl+C to shut down the database
abra app deploy YOURAPPDOMAIN
