Yes, positively it does. After reindexing all five indices of the table,
vacuum times have dropped from minutes to seconds. Looking at pg_class, it
is apparent that there was a cut in the number of tuples of about 30% for
all indices, but the number of pages dropped by about 90%!

Other people mentioned that this probably would get fixed in a forthcoming
release. Is there anything we can do in the meantime?

thanks
cl.
