+### Precheck
+
+* For support use https://git.pleroma.social/pleroma/pleroma-support or [community channels](https://git.pleroma.social/pleroma/pleroma#community-channels).
+* Please do a quick search to ensure no similar bug has been reported before. If the bug has not been addressed after 2 weeks, it's fine to bump it.
+* Try to ensure that the bug is actually related to the Pleroma backend. For example, if a bug happens in Pleroma-FE but not in Mastodon-FE or mobile clients, it's likely that the bug should be filed in [Pleroma-FE](https://git.pleroma.social/pleroma/pleroma-fe/issues/new) repository.

 7. If you installed a newer Pleroma version, you should run `mix ecto.migrate`[^1]. This task performs database migrations, if there were any.
 8. Restart the Pleroma service.
-9. After you've restarted Pleroma, you will notice that postgres will take up more cpu resources than usual. A lot in fact. To fix this you must do a VACUUM ANLAYZE. This can also be done while the instance is still running like so: 
-   $ sudo -u postgres psql pleroma_database_name
-   pleroma=# VACUUM ANALYZE;
+9. Run `sudo -Hu postgres vacuumdb --all --analyze-in-stages`. This will quickly generate the statistics so that postgres can properly plan queries.
