I don't know the database structure but assuming ever page has a primary key
sequence called p_id you would just have to

CREATE TABLE anchor (

a_id int primary key,
p_id int references page (p_id),
a_name varchar (100),
a_deleted boolean

);
CREATE TABLE anchor_ref (

a_id int references anchor (a_id),
p_id int references page (p_id),

);
The changes to database structure mentioned in bug #8955 seem to be very minor.

I'm not suggesting the same (supposedly extremely fragile interface) as in bug
#8955.
I'm suggesting a "What links here" function as for pages. If that interface is
bad why is it in use?

The suggested method would even allow to pick up dangling pointers to deleted
anchors,
because once an anchor entry existed and had anchor_refs pointing to it it could
not be deleted,
the anchor would merely be set to "a_deleted = true".

I do think it is worth the effort. Broken references to anchors can be a
nuisance for editors.

You wouldn't have to guess what "the same section is" (see bug #8928#c2).
An editor could rename a section and pick up the dangling pointers afterwards
or use a function to rename a section.
