You should rewrite your insert to receive multiple rows from single
select. This query shoud be similiar to this below:

insert into ... (..)
selectnextval('est_p_id_p'),id_activite,ref_resource,ref_jour
fromactivite, personne,groupe,fait_partie,jour
whereactivite.nom='..' and fait_partie.ref_groupe=groupe.id_groupeand groupe.nom='..'and jour.id_jour=3
