Dear all,

I know this problem could be sorted easily using statialdb but I'm
asking if is possible to do the same think in grass.

I have a vector layer that store db in posgtres. I'm able to extract
(v.extract) vector feature from this using sql query based on data
stored into an other table 2 into the postgres db.
The question is that if I change a value into the table 2 the vector
extracted does not reflect this changes but I have to run again

Dou you have any suggestion?
