OK, let me try to provide more details:

Overview

Generate a dotnetcore using postgres as backend database, frontend with Angular Framework

Reproduce error

Run the command jhipster-dotnetcore and select postgres database

Related Issue

As you can see, nothing have been generated for the postgres support, neither how to integrate it through docker and env. variable

Jhipster Version

Jhipster 8.10, Jhipster-dotnetcore 4.5

Suggest Fix

I guess it's a regression issue
