Failing tests: PG::UndefinedTable: ERROR: relation "categories" does not exist

[MuksSharma]

When using the supplied data (Dell sql) and running the whitelist scripts, there are following errors reported.

[2016-09-17T10:25:49.273854 #12780] ERROR -- : PG::UndefinedTable: ERROR:  relation "categories" does not exist
LINE 5:                WHERE a.attrelid = '"categories"'::regclass

                  ON a.attrelid = d.adrelid AND a.attnum = d.adnum
               WHERE a.attrelid = '"categories"'::regclass
                 AND a.attnum > 0 AND NOT a.attisdropped

 (ActiveRecord::StatementInvalid)

It seems to be the double-quotes for table names that is causing the issue.
