problem with pg_dump and pg_restore

Hi

I try to move my datas from a postresql 7.3.2 to a postgresql 7.4.1. The
database was dumped with:

pg_dumpall -g GLOBALobjects.sql
pg_dump -s DATABASE > DBschema.sql
pg_dump -Fc DATABASE > DBdata.tar

and rebuilt on the new system with:

createdb DATABASE
psql DATABASE < GLOBALobjects.sql
psql DATABASE < tsearch2.sql
psql DATABASE < DBschema.sql
pg_restore -N -a -v -d DATABASE DBdata.tar

All semms to go well except the restoring. pg_restore prints the
following report:

fi(at)susi179:/tmp> pg_restore -N -a -v -d codasdb codasdbdump-d.tar
pg_restore: connecting to database for restore
pg_restore: executing SEQUENCE SET anschrift_ansid_seq
:
pg_restore: executing SEQUENCE SET dokument_docnum_paper_seq
pg_restore: restoring data for table "linkthemen"
pg_restore: restoring data for table "links"
pg_restore: restoring data for table "anschrift"
pg_restore: restoring data for table "kontakt"
pg_restore: restoring data for table "mitarbeiter"
pg_restore: restoring data for table "kunde"
pg_restore: restoring data for table "kontaktperson"
pg_restore: restoring data for table "versuch"
pg_restore: [archiver (db)] could not execute query: ERROR: insert or
update on table "versuch" violates foreign key constraint "$1"
DETAIL: Key (proid)=(0) is not present in table "projekt".
pg_restore: *** aborted because of error

Why are the tables not restored or better dumped in the correct order?
Is there a solution to solve this problem?

Thanks for any help

Ulrich
