Aaron Kimball updated MAPREDUCE-840:
------------------------------------
Attachment: MAPREDUCE-840.patch
Attaching trivial patch for this issue. No new tests because I've only seen
this issue manifest in interacting with postgresql. I've verified that with
this fix in place, it works with postgresql. The TestDBJob unit test also works.

> other connections to the same table.
