v1-0001-Document-DSM-registry.patch (application/octet-stream)

With the functions GetNamedDSA and GetNamedDSHash added in fe07100
and the system view pg_dsm_registry_allocations (167ed8),
I think its time the DSM Registry get its own subsection in the documentation that connects all these.

Here’s a patch that changes the title of xfunc-shared-addin-after-startup into “DSM Registry”,
and updates the content of the section itself.
I thought about updating the id too, but I don’t think it’s strictly necessary.
