Direct links to edit documentation

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/12/runtime-config-wal.html
Description:

Would it be possible to add "edit this page" links to every PostgreSQL doc
page, pointing to the docs git repo, ideally on a site that allows
on-the-site editing without locally cloning i.e. github?  This will make it
far easier to contribute tiny changes like adding more links in the text.
For example, https://www.postgresql.org/docs/12/runtime-config-wal.html has
a lot of useful information, but many setting keywords are not links, making
it harder to find. Commenting on that page that a link is missing seems
silly, whereas if there was an edit button, users could have submitted their
edits directly.

Thanks!
