You failed to supply a rule covering the case OLD.idpessoal = 0.
More specifically, you *must* supply an unconditional INSTEAD rule to
replace the attempt to insert/update in the view. Possibly what you
want is
CREATE RULE "updateturnodocente" AS ON UPDATE TO "docentesturno"
WHERE OLD.idpessoal != 0
DO ( ... );
CREATE RULE "updateturnodocente_default" AS ON UPDATE TO "docentesturno"
DO INSTEAD NOTHING;
Here, the unconditional rule always fires, and the conditional one fires
only when its condition is true.
