Postgres WARNING: Errors are ignored during recovery: 59

I use the pg: transfer utility recommended by Heroku for loading and unloading databases. For instance:

heroku pg:transfer -f postgres://username:password@localhost/database-name -t postgres://user-name:password@host-name/database-name --confirm app-name

I was able to do this successfully, but every time he claims that the error was ignored at the end of the transfer:

WARNING: errors ignored on restore: 59

Do I need to worry about this?

EDIT:

I went through my conclusion and seemed to be wrong on every table. It seems that he discarded the sequence and then threw an error, stating that it does not exist.
