Authentication issues with new postgres (on CC7 kubernetes CI)

When launching a basic test on my dev machine using postgres default pod for CC7 kubernetes containers in CI, I am now getting an authentication error:

./run_systemtest.sh -e eos5-config-quarkdb-https.yaml -d internal_postgres.yaml -s tests/prepare_tests.sh -n toto -k
...
Configuring database:

Looks like this was caused by 1f9441c9

Postgres docker image was bumped from 9.6 to 14.10 for CC7 and Alma9 environment but it looks like CC7 should have stayed with older version only.
