That looks like data corruption on the original database.

Look at https://wiki.postgresql.org/wiki/Corruption and
follow the "VITALLY IMPORTANT FIRST RESPONSE".

Check if that is the only row that violates the constraint.
You could manually delete all offending rows on the source,
then dump/restore (don't continue working with the database
even if it seems consistent again).
