PG HA documentation - side navigation isn't unique
The links in the side navigation of a page seem to be generated from the titles of the markdown sections. The headings aren't unique, so the links aren't, and you can't meaningfully link to say the second Consul
section in the document.
Maybe we could take the document structure into account so Required Information / User information / Consul
gets #required_information__user_information_consul
as well as #consul
for the simple case.
