Hi Richard,
AFAIK QGIS needs a field which is defined as primary key field in one of
the tables contained in the view. If this is the case the values in the
field must be unique, too.

it depends on the QGis version
QGIS wants a unique id on postgis layers, so I created a view that includes:
ROW_NUMBER() OVER (ORDER BY mytable.ogc_fid ASC) AS row_num,
which seems to be a standard way to create a unique id on a view [1]
but QGIS does not see the row_num, i.e. it is not listed in the No
Suitable Key Column
