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.
