/* Note:
Preset data is not required in pagemeta as a simple join to page will surface these fields.
Version history table does not need these fields as they are populated once during page creation:
  -- you cannot mark an existing section as a preset
  -- a page is only marked as preset during it's creation (e.g. created from an existing preset)
