Hi, after updating postgresql from version 13 to 14 jupyterhub is not able to startup properly, showing a error message about authentication

_+ psql postgresql://jupyterhub:t5KRBP036Klwxxbd@jupyterhub-db:5432/postgres -q -c ‘SELECT 1’_

_psql: error: connection to server at “jupyterhub-db” (172.30.115.48), port 5432 failed: fe\_sendauth: error sending password authentication_

_+ ‘[’ 2 -eq 0 ‘]’_

_+ sleep 1_

Any idea or suggestion about how to fix this problem I appreciated in advanced.

Thanks!
