描述

During startup, if Redash fails to connect to Redis or Postgres it will raise an unexpected exception. We should catch these exceptions, showing a meaningful message and pointing the user to setup instructions to explain what Redash depends on.

研究方向
Examine Redash's startup code, likely in redash/ init .py or redash/settings.py, where connections to Redis and PostgreSQL are established. Catch the exceptions during connection attempts and display a meaningful error message that guides users to setup instructions. Look for existing exception handling patterns in the codebase and follow them.
