Radim,

Can you expand on this idea using g.copy? I tired db.copy with the  
command:

GRASS 6.1.cvs (arrowhead_utm):~ > db.copy from_driver=dbf  
from_database=./ from_table=townships to_driver=pg  
to_database="host=localhost,dbname=ts2325" to_table=townships

and got the error:

DBMI-DBF driver error:
Table 'townships' doesn't exist.
Error in db_open_select_cursor()

WARNING: Cannot open select cursor: 'select * from townships where 0  
= 1'
WARNING: Copy table failed

These messages imply that I need to create the Table  
"townships" (including all the columns and data typoes) before I can  
copy it from dbf. I was hoping to simply copy all the columns from  
the old dbf table to the new pg table
