I’ve looked through all the filters in the documentation and I didn’t noticed anything useful for this. Maybe I’ve omitted something.
I need to have access to all post data in one time, not just content or ID or title and so on.
I can hook up to edit_post or post_updated action probably, but this doesn’t help with data insertion.
EDIT:
Maybe I could use POST_ID to get post by get_post function, but it would be option only if there is no database call.
