描述

When investigating optimizer bugs, In order to rule out schema changes and other interactions with descriptor state, we should consider adding two things to statement diagnostics bundles:

  1. a list of all known schema changes for each schema object used by the statement
  2. the pretty-printed descriptor JSON for the descriptor of each schema object used by the statement
