Attention: To run Mattermost version 11 team edition with docker, you need to upgrade PostgreSQL to at least version 14.

Example of change in .env:

POSTGRES_IMAGE_TAG=14-alpine

It’s not a problem, but maybe updating the example.env file with correct examples would be more useful.

I tried changing this is my .env-file, but the postgres container complains about the database not being compatible. Is there something to be done for the database itself to upgrade it to version 14 of postgres?

Same issue with postgres versions here. I'll try the linked solution, but an official upgrade path (and also a recommended postgres version ?) would be welcomed
