Sorry for this /stupid/ question (might be time to go to sleep !)
I realize it must be related to a truncature operated between pg and
grass or something like it.
As it was annoying in a recursive query script, I turned the command in
this :
echo "select count(*) from table1 where attr=201"\
| db.select 2>/dev/null
Good evening ;-)
