postGIS vs. TAB files

[Paul Ramsey]

David,

Frank might have to comment on the efficiency of his TAB support in  
OGR to clarify, but in general PostGIS is more effective if you want  
to consolidate management of data into one place, query/modify the  
data from multiple applications/clients, and get better optimization  
of composite spatial/attribute queries.  In straight speed metrics of  
drawing a map, PostGIS vs shapefile favours the shapefile by 10-20%.   
I am not sure if the same would be true of TAB, they have to traverse  
an extra layer of abstraction (OGR).
