[postgis-users] Multipolygon an shape

[Stüwe Rolf]

Hallo,
 
I have a problem with a polygon:
I want to create a shape-File from a geometry, which is a multipolygon by definition
with the statement:
pgsql2shp -f abc verdis_beta wsw_shp 

 
 and  get the following error message:
 
ERROR: Cannot have multiple geometry types in a shapefile.
Use option -t(unimplemented currently,sorry...) to specify what type of geometry you want dumped
 
where is the error?
 
 
And another question:
I think that I perhaps have overlapping geometrys in my table and they can not build a shapefile.
When I tryed to take the function "overlaps" to test my table (with 600,000 polygons) , the duration is very long, even on a small part of my data. 
How can I accelerate  the overlaps-function ?
 
Regards Rolf Stüwe
