The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/plpgsql-statements.html Description:
So I do see that they are anchors for each section at the top of the page. I could have sworn that for some doc pages there was also an anchor symbol next to the subtopic. If you clicked the anchor it would change the URL to reflect the subtopic. If I am misremembering then mea culpa (though it would be a nice feature that I use on other doc sites) Thanks Steve
