Ok thanks everybody for the calrification, after all now I allready learned something new... ;)
My employer is currently thinking about migration to 8.2.x because of your feedback, so I think that the problem could be resolved... ;)
Thanks to everyone...

Up to 7.3, periodical REINDEX was needed to trim down bloated indexes.
Since 7.4, empty index pages are recycled so that's no longer necessary.
You can still end up with larger than necessary indexes in recent
versions under unusual access patterns, like if you delete all but a few
index tuples from each index page, but it's rare in practice. And it's
not unbounded growth like in <= 7.3.
In any case, the indexes won't become corrupt.
