Upgrade recommended postgres image to version 14.1

[Sanne]

Also removed --ulimit memlock=-1:-1 --memory-swappiness=0 from the recommended parameters in starting scripts: that's making bootstrap slightly faster on linux, but the difference is negligible and not worth the hassle as I've learned Mac users can't use these.

Failure is unrelated. Merging this

It would be nice to backport this, WDYT @gsmet ?

Please check the failures more carefully. They are related:

assert service.metadata.labels.get("app.kubernetes.io/version") == "10.6"
3920
       |       |        |      |                                |
3921
       |       |        |      '14.1'                           false
3922
       |       |        ['app.kubernetes.io/name':'postgres', 'app.kubernetes.io/version':'14.1']

So either we get a quick fix or this needs a revert.

[gsmet]

My guess is that this file shouldn't be changed and should be considered a static resource.

Ah crap, you're right, I was looking at the app.kubernetes.io/version and didn't notice it was related to the postgresql image change.
