Yes, use Osmosis to do it automatically.

Initialise with

osmosis --rrii

then modify the configuration file manually, and find the proper 
state.txt file that approximately matches your version of the data 
(explained approx. 100 times on this list, google for --rri), then
in regular intervals run

osmosis --rri --simc --wxc my-change-file.osc

and apply the my-change-file.osc to your database using osm2pgsql.

The new method takes a moment to set up but after that it's even easier 
than the old.
