[postgis-users] Some questions concerning postgis

[Neil.Young]

Now, that I have valid data in my db, the following questions arise:

1) The projection of the data is Gauss Krüger III. Possible to 
re-project to lets say EPSG 4326?
2) The polygons contain too much vertices. I would like to reduce it, 
but keep the common borders valid. Does anybody know, how this could be 
achieved?
