I've created an AKS cluster and Flexible PostgreSQL database.
The postgresql database is public, and I made firewall entry while setting up the DB to allow local connection from my IP - which worked fine.
When I then tried to connect from AKS, I was unable to - I was getting timeouts.
Eventually, I clicked the setting to allow access from everywhere on azure

That fixed the timeouts, and I can now connect, but I get a new error:
no pg_hba.conf entry for host "**.**.***.203"
What am I doing wrong?
