[postgis-users] Can postGIS database views work like .ARP project files?

[Mark Leslie]

PostGIS can contain any supported geometry type in the 'geometry' 
object, and they don't need to be of the same type within a single table 
or view.
If you define a geometry column using 'addGeometryColumn', you can 
define the geometry type as a single type (POLYGON, LINE, etc), or you 
can define it as GEOMETRY, and include a mix.
The difficulty will come when you try to connect a client app to the 
table to visualize.  I'm not sure if/how they will handle mixed feature 
types.
