Description

This PR will make sure that the gen4 planner does one of the following:

  • Produces a correct query (correct here means "does what the user wants", not necessarily the same thing that V3 did)
  • Produces a correct error (if the query is wrong, it should be detected and failed correctly)
  • Produce a Gen4NotSupported error. This makes it easy to fall back on V3 when gen4 does not yet support the query.
