I don't see anything but the filename length needing adjustment. In 
fact, when I hacked predicate.c to ignore the issue and use too high 
page numbers, I ended up with files like "100AB" in the directory. So 
slru.c goes merrily above the "limit", it just won't recognize them when 
it's time to truncate the slru because of the unexpected length, and 
will not clean them up.

(perhaps not worth risking it in 9.1 anyway, though..)
