Is the size of the hash bucket dependent on the number of buffers available ?
If so, with -B 30000, it might create huge hash buckets and hence the
hash join could degenerate to a nested loops join. Is that possible -- just
checking. What could be good values for -B and -S. The largest table I am
joining is about 60M
