text: Title: Add tests for all supported database providers
  Body: ## Problem
  
  <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] -->
  
  We currently do not run integration tests on all of the database providers we support as Prisma tests them themselves, however we should still run our own tests as there may be database specific functionality that causes errors with our client.
  
  ## Suggested solution
  
  <!-- A clear and concise description of what you want to happen. -->
  
  Add new integration tests for all supported database providers: https://www.prisma.io/docs/reference/database-reference/supported-databases
