Actually you are just dumping the table data.
More below.

Then I connect to the db, and verify that things are as expected.

In your \d task_instance above I do not see a trigger that calls
public.check_permission(). Does one exist or was it cut off the output
you pasted?
Also look in the dump file. Given that you are using 11.5 I'm going to
assume it is resetting the search_path and that the unqualified schema
name of permitted_work below is your issue.
QUERY: SELECT
permit FROM
permitted_work
WHERE
NEW.employee_key = permitted_work.employee_key
AND
NEW.work_type_key = permitted_work.work_type_key

After that error, U cannot see any objects in the table

Did not find any relations.

quiting psql and reconecting shows that the obkects ARE there, with the
taks)instance table empty.
What am I doing wrong?
