Hm.  I'm guessing that table is a child table, and this has something to
do with improper constraint inheritance.  Could we see psql \d+ output
for both this table and its parent?  And for good measure, maybe the
output of

SELECT conname,convalidated,conislocal,coninhcount,connoinherit
FROM pg_constraint WHERE conrelid = 'js_activity_20110101'::regclass;

and likewise for the parent table.
