Wasn’t the asker’s goal a front-end to Postgres?

Your product looks interesting but I don’t see how it fits the requirements here.

Thanks, yeah you're totally right, but worth mentioning if OP had never considered backing an app with a spreadsheet.

It's a really powerful option for non developers to manage data without having to use SQL / a PG client etc.

Unfortunately, for the current project(s) I have to work with existing DBs. That said, your product looks great for the use case!
