Using the Azure portal:

1. Select your Azure Database for PostgreSQL flexible server.

2. In the resource menu, select Networking.

   

3. If you want to delete a firewall rule, select the icon that resembles a trash bin, which is located to the right of the rule definition.

   

4. If you want to delete the firewall rule that allows connections originating from any IP address allocated to any Azure service or asset, clear the Allow public access from any Azure service within Azure to this server checkbox.

   

5. Select Save.

   

6. A notification informs you that the changes are being applied.

   

7. Also, the status of the server changes to Updating.

   

8. When the process completes, a notification informs you that the changes were applied.

   

9. Кроме того, состояние сервера изменяется на Ready.

   

You can delete firewall rules from a server via the az postgres flexible-server firewall-rule delete command.

az postgres flexible-server firewall-rule delete \
  --resource-group <resource_group> \
  --name <server> \
  --rule-name <rule>

If you attempt to delete a firewall rule on a server which isn't in Ready state, you receive an error like this:

Code: InternalServerError
Message: An unexpected error occured while processing the request. Tracking ID: '<tracking_id>'

If you attempt to delete a firewall rule with an invalid name, you receive an error like this:

The firewall rule name can only contain 0-9, a-z, A-Z, '-' and '_'. Additionally, the name of the firewall rule must be at least 3 characters and no more than 128 characters in length. 

If you attempt to remove a firewall rule from a server that doesn't have public access enabled, you receive an error like this:

Firewall rule operations cannot be requested for a private access enabled server.
