Thanks Tom, I will review those changes tonight. In the meantime, to
reproduce, I run the following:

- createdb test
- create some tables, I used a simple loop to create 10 empty ones.
- pg_dump -v -Fc test | tee test.dump > /dev/null (so it's through a
pipe, same as if the file is streamed through curl which was the
original case)
- pg_restore -j4 --verbose --clean --no-acl --no-owner -d test test.dump

That should fail consistently. pg_restore_12 and pg_dump_12. Same
passes in if I run in earlier versions.

I just tried that and didn't encounter any errors.

I did:

pg_dump -d production -U postgres -Fc |tee test.dump > /dev/null

pg_restore -j4 -d production_test -U postgres test.dump

pg_restore: error: could not find block ID 4804 in archive -- possibly due to out-of-order restore request, which cannot be handled due to lack of data offsets in archive pg_restore: error: could not find block ID 4806 in archive -- possibly due to out-of-order restore request, which cannot be handled due to lack of data offsets in archive
pg_restore: error: a worker process died unexpectedly


Whereas a restore without -j4 succeeded.


Please come up with a more complete example.

Are you OS user "postgres" when you run that?


Yours,
Laurenz Albe
