I have a very confusing isse. I am trying to backup and restre a signle
table .

first I dump the table.

]0;stan@smokey: ~stan@smokey:~$ pg_dump -a --table task_instance  > task_instance.dump

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

]0;stan@smokey: ~stan@smokey:~$ psql
psql (11.5 (Ubuntu 11.5-3.pgdg18.04+1))
Type "help" for help.

Then I delete the rows from the table.

DELETE 31

Then I try to restore from the dump file.

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

quiting psql and reconecting shows that the obkects ARE there, with the
taks)instance table  empty.

What am I doing wrong?
