  DB Types in column.valid_target_types are not in sync with the types returned in database types endpoint
  ## Description
  * `valid_target_types` property of column returns "DOUBLE PRECISION"
     - Endpoint: /api/v0/tables/14/columns/
  * Types endpoint returns mathesar types where Number has the db type "DOUBLE_PRECISION"
     - http://localhost:8000/api/v0/databases/1/types/
     - Mathesar type: Number
  
  Note that "DOUBLE PRECISION" and "DOUBLE_PRECISION" differ from each other.
  
  ## Expected behavior
  Both endpoints should return values with same spelling.
