apply changeset from apidb schema database to mapnik

Hi

I have tail server with mapnik and database created via osm2pgsql, and 2nd database for potlatch with apidb-0.6 schema for potlatch.

Is there any way to apply change i made in potlach to database that mapnik use ? Now i have to apply those changes to osm file and load whole file to database which takes about 30 minutes for Poland (over 3GB osm file).
There have to be better way to do this… i hope.

and the same problem is with apply those change to obf file that OsmAnd use…

Any idea ? any advice ?
