I was just upgrading FreshRSS and PostgreSQL containers to the latest images. (see tutorial FreshRSS: A free, self-hostable news feed aggregator)

After getting the images, stopping the containers, and doing an Action -> Clear to get the latest image I found that the FreshRSS container wouldn't restart and logged the error.

Start container FreshRSS failed: {"message":"Cannot link to a non running container: /PostgreSQL AS /FreshRSS/psql_server"}.

The FreshRSS container uses a Link setting to the PostgreSQL container (sorta-like an inter-container hosts config). My FreshRSS link setting has container 'PostgreSQL' aliased as 'psql_server' (as per the error message). I was able to fix the issue by deleting the current link and adding a new one by reselecting the same PostgreSQL container and the same alias text as before.

I've upgraded just the FreshRSS image before without this error so the link must reference something that doesn't get updated when a linked container is upgraded.
