+  - The primary key for the `User` table will be changed. If it partially fails, the table could be left without primary key constraint.
+  - A unique constraint covering the columns `[clerkId,tenantId]` on the table `User` will be added. If there are existing duplicate values, this will fail.
+  - Added the required column `tenantId` to the `User` table without a default value. This is not possible if the table is not empty.
