> Don't you miss for each subselect an order by tid ?
No: since all the SELECTs are part of one statement, they
will have the same (pseudo-random) implicit order. Since
Josh's requirement said the order of the tids* was not important,
I can be lazy and get away with it in this case. An order by
would not hurt, of course.
* As far as PG goes, this is not an ideal abbreviation! :)
