First it didn't give me anything (0 rows). After I recreated the constraint
triggers:
CREATE CONSTRAINT TRIGGER "fk_folders__parent" AFTER INSERT OR UPDATE ON
"folders" NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE
PROCEDURE "RI_FKey_check_ins" ('fk_folders__parent', 'folders', 'folders',
'UNSPECIFIED', 'parent', 'nr');
CREATE CONSTRAINT TRIGGER "fk_folders__parent" AFTER DELETE ON
"folders" NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE
PROCEDURE "RI_FKey_noaction_del" ('fk_folders__parent', 'folders',
'folders', 'UNSPECIFIED', 'parent', 'nr');
CREATE CONSTRAINT TRIGGER "fk_folders__parent" AFTER UPDATE ON
"folders" NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE
PROCEDURE "RI_FKey_noaction_upd" ('fk_folders__parent', 'folders',
'folders', 'UNSPECIFIED', 'parent', 'nr');
the above query returned three rows:
jeroenv=> select * from pg_trigger where tgconstrname='fk_folders__parent' ;
tgrelid | tgname | tgfoid | tgtype | tgenabled |
tgisconstr
aint | tgconstrname | tgconstrrelid | tgdeferrable | tginitdeferred |

(3 rows)
But the same query (update folders set title='Sitemap' where nr=43) still
crashes the backend at exactly the same spot.
So, still no clue.
Thanks,
