When running

prisma migrate dev --preview-feature

with prisma 2.14.0, I get the following error:

Error: A migration failed when applied to the shadow database:
P3006
Migration `20210128090300_init` failed to apply cleanly to a temporary database. 
ERROR 42000 (1142): ALTER command denied to user

I think the problem is that the database user does not have the required access to the shadow database. Only granting

CREATE, DROP ON *.*

like stated in the docs, seems to be not sufficient.

Hi Pascal, we’ll double check that soon and let you know, it’s possible that the docs needs to be updated

Thanks, I just granted all permission for now, which solves the problem.
