Yes. If you have not done so already, install pgadmin: https://www.pgadmin.org/download/
Then open pgadmin, create a new database and remember (copy) the database’s name.
Then go to Menidx Studio Pro, in the project explorer go to ‘Settings’
After you have started the app, a popup occurs “Synchronise database?”. Once the app has been started, you can have a look at pgadmin and you will see that the database now contains your local app-data.
Well, if you deploy it onto a cloud node, there will be a postgresql used beneath it anyways.
Is your question related to your local Studio Pro development environment?
You can switch and move away from the locally embedded database to a locally installed postgresql. Is this what you intend?
