An ETL "job" runs inside its own transaction and consists of a series of queries that transform the data from staging tables to the destination tables. If a failure occurs, the transaction rolls back so there's no "debris" left over -- which makes troubleshooting very difficult.
If you are loading huge amount of data then:
1) Committing every 10000 (or so) rows might make sense
2) Have you considered using COPY API in Postgres' JDBC?
3) Which version of PostgreSQL are you using? I guess 9.3 has a freeze option which might help you. I am not sure if the API supports it.
