[GRASS-dev] d.vect.thematic fails if db.connect and v.db.connect are different

Hi,

I don't know if this is a bug or a feature, but when I have a location for which I have set a database connection with db.connect, and then set a different database connection for one vector map with v.db.connect, d.vect.thematic looks for the vector map attributes in the database defined by db.connect:

GRASS 6.1.0RC1 (spearfish60):~ > db.connect -p
driver:pg
database:belgique
schema:(null)
group:(null)

GRASS 6.1.0RC1 (spearfish60):~ > v.db.connect -p fields
Vector map <fields> is connected by:
layer <1> table <fields> in database </home/mlennert/GRASS/DATA/spearfish60/PERMANENT/dbf/> through driver <dbf> with key <cat>

DBMI-Postgres driver error:
Cannot connect to Postgres: FATAL: la base de données «/home/mlennert/GRASS/DATA/spearfish60/PERMANENT/dbf/» n'existe pas
(meaning the database does not exist)

Moritz,

the best way to figure out what's happening is to
edit d.vect.thematic in the GISBASE/scripts/ and to
add -x there in the #!/bin/sh line:

#!/bin/sh -x

Then it will print all executed commands and variable values
step by step.
