- Drop table statements for all tables to avoid duplicates in case of wf rerun
- Add pdfsaggregated step to create the indi_is_result_accessible table. This step is executed on the new impala cluster only, since the pdfaggregation_i is updated on this cluster.
1. Remove tables/views from old databases in the new cluster, before dropping the dbs
2. Fix id in result_accessroute, indi_impact_measures, indi_pub_bronze_oa
1. Remove external table definitions in stats_ext
2. Fix the issue where some views are not created.
3. Added two workflow parameters for copying also the usage stats dbs
