Description: Cannot create foreign key constraint
Details:

pg_restore generates the following error:
pg_restore: [archiver (db)] Error from TOC entry 2950; 16386 17827531 FK
CONSTRA INT asientry_r0 tigris
pg_restore: [archiver (db)] could not execute query: ERROR: insert or
update on table "asientry" violates foreign key constraint "asientry_r0"
DETAIL: Key (pid)=(AA0003403544) is not present in table "pobject".
Command was: ALTER TABLE ONLY asientry
ADD CONSTRAINT asientry_r0 FOREIGN KEY (pid) REFERENCES pobject(pid);

Also running the alter table after restore generates same constraint
violation error.

The following query returns one row:

select * from asientry, pobject
where pobject.pid = 'AA0003403544'
and pobject.pid = asientry.pid;

Any ideas
