Comment 2 for bug 1374091

Well this does speed up search, but we just found out that it seems to only pass up the uncontrolled values for us now, not the coded value ones.

The coalesce part of the select is only grabbing the first value for our system.

Sample outputs pre-change and post-change with the branch for...

SELECT * FROM metabib.record_attr_flat WHERE id = 1348457 ORDER BY attr;

I'm not sure yet, but this seems to affect things like acquisitions loading and matching. Further testing pending.
