Hi Ahmet,
It seems to be a bit more complicated. I've currently got a string going on
exactly the same topic here:
http://osgeo-org.1803224.n2.nabble.com/Joining-vectors-by-location-td7016528.htmlMy experience up to this point seems to point to the fact that it would be
easier to put the data into a PostGIS database and perhaps to use the
PostGIS functions after that, but I've not yet been successful in that
area. Am getting close though:)Best,

Daniel,
I've taken a look at the thread; if I understand correctly, your current issue is permissions.
Database permissions in Grass-GIS are stored by mapset - you can only have one set of database parameters stored for one mapset. Moving data between database types is simplest and most reliable if you use different mapsets for different databases.
Hence: if you've created maps with DBF permissions, I suggest:
1. create new mapset, and enter Grass-GIS in the new mapset.
2. set database connection for new mapset using db.connect and db.login
3. use g.copy vect=map@oldmapset,map (running in the target mapset)
This will create the tables in the target mapset, linked to maps in the target.
Note that you have to present the right credentials to PostGIS - owner and password.
