auto increment field

Hello, I have two doubts, I use postgres 11:
1-) How do I create an auto increment field?
2-) What type should I use for image? I will send the image in base64.

Currently Data Modeler only supports SERIAL "type" (an alias) for Postgres. It's not an identity field, but an INTEGER field with an underlying SEQUENCE and TRIGGER generated under the hood by Postgres.
But you can use Computed field to manually type the identity field explicitly:

Hello, I tried to do as I received them the following message:

It is not possible to retrieve the Id for the "category" table. Unsupported data type for Id "id" field

Indeed, unfortunately for exporting to Aurelius classes, it's not supported.
