List parameters with modified defaults

Using the Azure portal:

1. Select your Azure Database for PostgreSQL flexible server instance.

2. In the resource menu, under Settings, select Parameters.

   

3. Select the Modified tab. The page shows a list of parameters whose currently set value deviates from the default.

   

You can list all parameters whose values are modified from defaults, via the az postgres flexible-server parameter list command.

az postgres flexible-server parameter list \
  --resource-group <resource_group> \
  --server-name <server> \
  --query "[?value!=defaultValue && isReadOnly==\`false\` && name!='temp_tablespaces' && name!='vacuum_cost_page_miss'] | [].name"
