I have connected my v0 project to Neon, and have enabled Preview branching. When I deploy changes to preview branch, it automatically creates a new Neon database. I was under the impression that any schema changes that I push through v0 would go into that branch but they are still going into the main prod branch. Also, when I merge the preview into production should the databases also be merged or changes brought across from preview branch into the production (although it seems any new db features I am generating from v0 are directly going into prod anyway, which defeats the purpose). If you can help will be appreciated.
