Truncate does reclaim space. Bulk deletes do not. If you are doing bulk
deletes since you need to delete *almost* everything consider using
"cluster" to clean up. It is much faster and gives you new unbloated
indexes. You may find pg_reorg of interest as well.

This issue, perhaps?:

In which case the data was not actually lost but could be missing from
the index (with the obvious potential for resulting corruption). It has
been fixed in current versions.
