I'm trying to understand the ID mechanism in
wp_posts in WordPress.
Whenever I add a product (woocommerce), page, or an image, they are recorded in
wp_posts and assigned an incremented id. Let's say, I added 100 items. The id of the last item would be 100. Then I removed 50 of them. The next item I add will have the id 101, not 51. So this id mechanism doesn't check the existing items for the next generated id. Last used id must be stored internally. How/where can I find it?
This is a follow up to another question os SO.
