[GRASSLIST:5692] Re: 6.0beta2: Input sites?

[Francesco Mirabella]

Hi Jose',
I found a similar problem with v.in.ascii as I got 
"database connection non defined" both for dbf and postgres. Also, I
found that after db.connect, db.login the v.in.ascii command did not
create the table in the database (i.e. "DBMI-postgres: error could not
connect to database").
However I did not get any reply, I hope it is not only a problem on our
two....
I post the message as I hope someone can provide a hint or tell us where
we are wrong

best wishes,
Francesco
