Thread: pg_restore problem

I got this error message:
pg_restore: [archiver] input file does not appear to be a valid archive

after the command:
pg_restore -d mydb_name mydb_name.dump.tar

the tar file was created with the command
pg_dump -b -f mydb_name.dump.tar -F t mydb_name

======
This is exactly what is said in the Man pages in pg_dump and pg_restore.
I am using postgres 7.3.1

My question: Is this a bug in the new release? Or I am totally stupid.

Help would be appreciated.
