I started with Pocketbase but the limitation around not supporting NULLABLE columns despite being based on SQLITE was starting to become a bit of a liability, so I switched to Trailbase a little while ago.
Switching DBs is very invasive. Switching your application base even more so. As long as you're happy happy with PocketBase and there's nothing you're critically missing, the answer will almost certainly be: no. Is there anything you're looking for?
