BUG REPORT

Please describe the issue you observed:

• What did you do?
  ./workload run tpcc "postgres://root@1.2.3.4:26257/tpcc?sslmode=verify-full&sslrootcert=/home/core/cert/ca.crt&sslcert=/home/core/cert/client.root.crt&sslkey=/home/core/cert/client.root.key" --warehouses=100 --drop --init

• What did you expect to see?
  init db with tpcc data

• What did you see instead?
  Error: failed insert into warehouse: pq: there is no unique or exclusion constraint matching the ON CONFLICT specification
  problem occurred with https://edge-binaries.cockroachdb.com/cockroach/workload.LATEST from 2018/07/24.
  Reverting back to older bin worked fine.
  Unfortunately workload does not expose version info (suggest to add -v switch for making support easier)
