commit 6854ddfdc114d26239aa22ff453fa12a2a1a7a26
Author: Dan Scott <dan at coffeecode.net>

    LP#783486: Improve authority lookup performance
    
    Testing showed that the two indexes added herein improve
    authority lookup performance radically; on a 16 GB RAM
    database server with 1.1M records, lookup times decreased
    from 5500 ms to 0.223 ms. Recommended, would EXPLAIN ANALYZE
    again.
