Reads a request_json column. Anything unreadable is treated as no stored
request, and so is a request without its list or one that names a
capability outside the catalogue: the caller derives the request from the
source again. The result is rebuilt field by field, so it holds catalogue
names and nothing the column carried beyond the request.
