[postgis-users] Loading multiple shapefiles with different schemas into the same PostGIS layer

[Stefan Keller]

If table structures (and even formats) are different and you want to
automate it without programming, I would recommend an upcoming ETL
tool called GeoKettle from Univ. Laval, Canada:

> 4. Run the edited SQL scripts for each of the remaining shapefiles.
