Is there a maximum amount of pages for a multi-page post?

If your entire page fits in the 4GB LONGTEXT post content field, the limit to the number of pages would be related to the amount of RAM available on your server. When a multipage post is loaded, it is exploded on <!--nextpage--> to put your post into an array of individual pages, so at that point your single page load is consuming at least twice the total size of the post. If that exceeds the available RAM, PHP will throw a fatal error and execution will halt.
