PostgreSQL update causing issues

[ppfeufer]

Describe the issue

Docker install of Weblate.

After a git pull of this repo on the machine my instance is hosted it pukked in this update (0041e3a), which updates PostgreSQL from version 15 to 16.

Now after restarting docker, I'm facing this error:

database_1  | 2023-10-21 09:07:54.924 UTC [1] DETAIL:  The data directory was initialized by PostgreSQL version 15, which is not compatible with this version 16.0.

I already tried

• I've read and searched the documentation.
• I've searched for similar issues in this repository.

Steps to reproduce the behavior

• Update the local clone of this repo via git pull which pulls in 0041e3a
• Restart docker

Expected behavior

Weblate is to be starting and PostgreSQL is being migrated to the new version without throwing a tantrum.

Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

### Additional context

Overriding the database image in `docker-compose.override.yml` and set it to `image: postgres:15-alpine` fixes it, for the time being …

This issue has been marked as a question by a Weblate team member. Why? Because it belongs more to the professional Weblate Care or community Discussions than here. We strive to answer these reasonably fast here, too, but purchasing the support subscription is more responsible and faster for your business. And it makes Weblate stronger as well. Thanks!

In case your question is already answered, making a donation is the right way to say thank you!

[ppfeufer]

Ah, thank you so much! Worked like a charm.

A quick hint in the changelog would be nice for future updates like this. :-)

PS.:
In the docu the DB volume is named weblate-docker_postgres-data but it's weblate_postgres-data.

The volume name contains name of the directory where docker-compose files are. You've stored that in weblate, while the whole documentation uses weblate-docker here.

[ppfeufer]

Ah I see, thanks for the clarification.
