This is great, but as convenient as Obsidian Sync is, it'll never replace plain Git (for me) until it has unlimited version history:
> The retention period for your version history depends on your Obsidian Sync plan. On the Standard plan, notes are retained for 1 month, while on the Plus plan, they are kept for 12 months. After this period, older versions of your notes are deleted.
It also won't replace Postgres, because that is also a different thing.
You can use this to sync changes in (near) realtime and then either commit them to git, or use some other mechanism to increase retention.
