You are using grass6.4, I suppose ? In that version v.in.ogr does not 
have a key parameter.

Could you send us the output of

v.db.connect -p patch_test1

and

v.info -c patch_test1

?

Also, I don't really understand the sens of your v.patch:

v.patch -e input=patch_map1 output=patch_map6

Why only one input map ? Doing that is somewhat like copying patch_map1 
to patch_map6...

If patch_map6 already exists and you want to append patch_map1 to it, 
then you have to use the '-a' flag.
