There's a pair of Postgres instances (clouddb-wikilabels-01,02) in the infrastructure clouddb-services project that need to be upgraded to Buster or Bullseye.
The database contents seem fairly small:
postgres=# SELECT datname, pg_size_pretty(pg_database_size(datname)) FROM pg_database; datname | pg_size_pretty -------------------+---------------- postgres | 7079 kB u_wikilabels_test | 58 MB template1 | 6969 kB template0 | 6969 kB u_wikilabels | 163 MB s52524_rwtest | 7103 kB (6 rows)
Not sure why this is living in clouddb-services? https://wikitech.wikimedia.org/wiki/Wikilabels suggests those were previously running on bare metal in the prod realm, maybe those were just simply pushed to the clouddb-services project as a first step. Anyways these instances seem to be only serving a single project so it's worth considering if we can push the maintenance of this rather small service to the people who actually use it.
