Description

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.

Contributor guide

Research direction
Investigate the startup code in Redash to identify where connections to Redis and Postgres are made. Catch the connection exceptions and modify the error output to display a meaningful message with setup instructions.
