Thanks for your help,

Unfortunately, it just complains:

ERROR: missing FROM-clause entry for table "wave_end_demand"
LINE 4: ON (core.demand.id = viwcs.wave_end_demand.demand_id)

Incidentally, I don't think that this particular re-ordering will make
much difference: viwcs.previous_wave is a table with a single row, and 3
columns in it. Here are the bits of schema, if they're helpful.
