Also i must that these lost triggers implement the parent table
side of the constraint, e.g.
CREATE TABLE VslSections(
id serial NOT NULL UNIQUE PRIMARY KEY,
name varchar(20) NOT NULL UNIQUE);
CREATE TABLE MachClasses(
id serial NOT NULL UNIQUE PRIMARY KEY,
name varchar(20) NOT NULL UNIQUE,
vslsecid int4 NOT NULL,
FOREIGN KEY (vslsecid) REFERENCES VslSections (id));
Then the triggers created are :
1)
CREATE CONSTRAINT TRIGGER "<unnamed>" AFTER INSERT OR UPDATE ON
"machclasses" FROM "vslsections" NOT DEFERRABLE INITIALLY IMMEDIATE FOR
EACH ROW EXECUTE PROCEDURE "RI_FKey_check_ins" ('<unnamed>',
'machclasses', 'vslsections', 'UNSPECIFIED', 'vslsecid', 'id');
2)
CREATE CONSTRAINT TRIGGER "<unnamed>" AFTER DELETE ON "vslsections" FROM
"machclasses" NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE
PROCEDURE "RI_FKey_noaction_del" ('<unnamed>', 'machclasses',
'vslsections', 'UNSPECIFIED', 'vslsecid', 'id');
3)
CREATE CONSTRAINT TRIGGER "<unnamed>" AFTER UPDATE ON "vslsections" FROM
"machclasses" NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE
PROCEDURE "RI_FKey_noaction_upd" ('<unnamed>', 'machclasses',
'vslsections', 'UNSPECIFIED', 'vslsecid', 'id');
The *LOST* triggers are 2 and 3.
