/* Postdata format:
*
* The Postdata array is a simple intermediate data format
* for the Post content and metadata.
* It is slightly abstracted from the SQL format itself but will
* only reformat keys, *not* do any alteration of the data itself.
*
* Any supported fields will be integrated into the database.
* Other fields will be saved in a JSON structure, and will
* be restored afterward.
*
* The following fields are mandatory for *writing*
* - path: String, must be sanitized to consist of just alphanumeric
* characters, `_-./`
* used to identify the post itself
*
* The following fields may be returned by the database:
* - id
* - created_at
* - updated_at
* - view_count
*
* The following fields may be supported by the database:
* - markdown: String, markdown of the post. May be
* stored separately and won't be returned by default!
* - type: String, defining the type of the post
* - title: String, self-explanatory
* - tags: Array of strings
* - settings: Hash, recursively merged settings (calculated by DB!)
*
* The following fields are *recommended*, but nothing more:
* - icon: String, optionally defining
