For executing and fetching query results, please also take a look at
existing system in sql.js where custom handler is written for
#sqlqueryform.ajax. So I think you could just pass the query to this
existing system and page replacing will happen.

About pushing subsequent sql result pages to AJAX.cache, I think it is
not required and is not done right now. We currently push to
AJAX.cache when user switches between different tabs etc. and not for
subsequent sql result pages.

So console div would be out of page_content and will not be
removed/replaced as queries get executed from the console. For this
also, I think you can write a custom handler.
