Hmm, that is beyond me.

1) I did notice that the pg_restore errors all where; ERROR: permission
denied for schema strans

2) They all occurred during CREATE INDEX or COPY, which would be the
part where --jobs kicks in.

To me it looks like out of order execution where the jobs starting on
their tasks before the main task got done granting permissions. I just
have no idea how that could happen.
