I like to have the all the docs as pinned tabs in Firefox. When a doc html does not have an icon it is not possible to distinguish it from the others. So I add this <link> tag to the <head> tag in postgresql html pages:
<link rel="shortcut icon" href="favicon.ico" />
The icon is the one from the site and is included in the same directory.
Would it be possible to include it in the next release to make it convenient to have the docs in a Firefox pinned tab?
