Generally, getting good performance out of PostgreSQL 7.2 is also impossible and economically inviable. You can either put resources toward upgrading to a newer version, which will fix many of the performance issues here, or toward changes to the old version that are not guaranteed to actually improve anything.
That said, a look into the write-caching+BBU policy on your controller is worthwhile. If you're running this application successfully on some hardware but not others, that could be a source for the difference.
