Case-insensitive filtering does not work

Bug description

Case-insensitive filtering doesn’t work. Intellisense isn’t picking up any properties named ‘mode’ anywhere in the options for where. Error thrown is “Unknown arg ‘mode’”

How to reproduce

Enable the preview feature in schema.prisma and add mode: ‘insensitive’ to the query.

return await db.user.findMany({
  where: {
    name: { contains: userName, mode: 'insensitive' }, // throws error
    // also fails inside of OR
    OR: [
      {
        name: { contains: userQuery, mode: 'insensitive' }, // throws error
      },
      {
        email: { contains: userQuery },
      },
    ],
  },
  select: { email: true, id: true, name: true },
})

Expected behavior

Case-insensitive filtering should work.

I figured out what was going on. For some reason the datasource provider contained both sqlite and postgres. Removing sqlite so that just postgres remained solved the problem.

I filed this bug before 2.8.0 was released and took that screenshot on 2.7.1 with the feature flag enabled. Though I did upgrade to 2.8.0 and remove the previewFeature flag, the error remains.
