Thanks. This does work of course, however I forgot to mention that the
query must filter out any duplicates in the 'log' table. Simplified:

time | host    | url
-----+---------+--------
001  | dec.com | index
003  | dec.com | index
011  | dec.com | index
015  | dec.com | content
057  | xyz.com | index


desired result:

host    | hits
--------+-----
dec.com | 2
xyz.com | 1
