The PublishPress Statuses plugin uses up to three different taxonomies to store the custom statuses.
- post_status is the taxonomy for pre-publication statuses.
- post_visibility_pp is the taxonomy for privacy statuses.
- post_status_core_wp_pp is the taxonomy for core WordPress statuses.
In general, terms are created in those taxonomies only under these conditions:
- A new status is defined by the user.
- A status has one or more of its properties modified.
The statuses which the plugin makes available by default are fundamentally defined by the plugin code itself, not by an entry in the _options database table. Status ordering does use option table storage, if the order is modified or a new status added.
