This is fixed (or at least greatly improved) in 7.4. Don't suppose
you'd care to run a test version and see if it actually prevents index
bloat for your usage pattern?
In earlier releases there is very little you can do about it; the only
solutions are regular reindexing or modifying your application to keep
the range of index keys from changing. The latter is generally
impractical...
