Hi Sylvain thanks for your anwers!
But it looks like I have a problem now... 1. I need to keep the tables ways, rels and nodes because of the diff updates 2. Those 3 tables will continue growing up with each new diff, until I reach the storage capacity of the server The only solution I see is a post-processing that will erase from PostGIS all the nodes lying outside my bounding box + all the ways using one of thses nodes + all the relations using one of thses nodes or one of these ways. Except if anyone else has a magical solution... Cheers Stéphane -- "Le mot progrès n'aura aucun sens tant qu'il y aura des enfants malheureux" -- Albert Einstein "A journey does not need reasons.
