Hmm.  I put this function into 7.4.5, minus the explicit cast to int8,
and it worked just fine (I used a debugger to verify directly that the
last SELECT was producing an indexscan plan).  I don't see anything in
the CVS logs to suggest that there was a related bug fix between 7.4.2
and 7.4.5.  So I'm baffled why it didn't work for you.  Ideas anyone?
