Comment 4 for bug 1730758

I applied Mike's fix on a 3.0.2 test server. Previously, I had bib records with located URIs which had a null vis_attr_vector; after running the upgrade script, that field was now populated. In addition, manually setting a record's vis_attr_vector to null and then adding a located URI to the record caused the vis_attr_vector to be correctly (re)populated.

I still can't retrieve these records in the public OPAC, as noted in bug 1736419, but the fix does appear to resolve the narrower issue described in this bug.
