If your solution to an issue is "just reset the Redis cache", this is when I am done.
Immich solves the wrong problem. I just want the household to share photos - I don't want to host a Google Photos for others.
Upgrades are frequent but no hassle.
I have been running this for half a year. It might have been more work earlier?
My household is using this for our shared photos repository and everyone can use it. Even the kids.
There is both direct web access and an iPhone app.
Of course, you may have reasons to do that. But then you also own the maintenance.
I have never had to maintain any PG extensions. Whatever they put in the image, I just run. And so far it has just worked. Upgrades are frequent and nothing has broken on upgrade - yet at least
