I get you now - you expected that the underlying table would
be updated if you change a variable in PL/pgSQL.
I don't think that you need dynamic SQL for that -
all it takes is an UPDATE statement in your loop, like
UPDATE XXX SET XXX.myfield = mynewvalue
WHERE XXX.pkey = ventilation_local.pkey;
(using the names from your sample)
