In 9.6, the HTML doc build's index entry for "data type" looks like

data type, Data Types
    base, The PostgreSQL Type System
    category, Overview
    composite, The PostgreSQL Type System
    constant, Constants of Other Types
    conversion, Type Conversion
    enumerated (enum), Enumerated Types
    internal organization, Base Types in C-Language Functions
    numeric, Numeric Types
    type cast, Type Casts
    user-defined, User-defined Types

where each of the phrases on the right is a hyperlink to a section.
Fine.  But in HEAD we get

data type, Data Types, Numeric Types, Enumerated Types, Domain Types, Type =
Conversion, The PostgreSQL Type System, The PostgreSQL Type System, The Pos=
tgreSQL Type System, Polymorphic Types, Base Types in C-Language Functions,=
 User-defined Types
    base, The PostgreSQL Type System
    category, Overview
    composite, The PostgreSQL Type System
    constant, Constants of Other Types
    container, The PostgreSQL Type System
    conversion, Type Conversion
    domain, Domain Types
    enumerated (enum), Enumerated Types
    internal organization, Base Types in C-Language Functions
    numeric, Numeric Types
    polymorphic, Polymorphic Types
    type cast, Type Casts
    user-defined, User-defined Types

How do we get rid of those duplicative (and not-appropriate-to-the-
main-topic) links on the first line?

v10 has the same disease, though not quite as bad as HEAD
because I just added some more <indexterm> items in HEAD.
