in a later post you mentioned using mapnik. I suppose you are importing
into a pgsql database with a mapnik schema.
So you are applying diffs with osm2pgsql.
For that tool it can work with bounding boxes but as ways and relation
diffs have no geometry they will all go into the database. You have to
get rid of these regularly.
I'm doing this with a cronjob calling a cleanup query.
If you really asking about osmosis: Sorry I have never used it to update
a database, only updating full planet files.
