Newly created blog is not reflecting in dynamic pages when app already running in production

[balakumar104]

I already have 8 blogs in DB, when using "gatsby build" those blogs are created as new pages using createpages flow through gatsby.node.js and when running the site, dynamically created blogs are working fine,

But when new blog added in DB, then its not getting created as a new page in runtime, so when click on the new blog I'm getting "404" page not found error .

Please let me know, if there is any possibility to create a dynamic page when new blog added in DB without rebuilding the site,
since we can't ask client to rebuild the site after every update.

Thank you
