I think this proposal goes a bit too far into implementation-dependent
details. The namespace of tables and indexes is clearly important, but
for example, the subdivision of types into range types and multi-range
types is really low-level and not usually practically relevant. And you
don't mention array types, probably because they are not mentioned in
typtype, but they are also relevant for the namespace of types. There
are multiple ways to slice all this, but it's not clear why we need to
lay this all out in the introductory documentation.
