[GRASS5] db.execute and min() max()-SQL-functions

Dear developers,

I am trying to figure out my min and max-values of my attribute-date
stored in PG.

steph@kermit:~ > echo "SELECT min(categorie), max(categorie) FROM
tk25_9_poly;"|db.execute
DBMI-Postgres driver error:
Cannot execute:
SELECT min(categorie), max(categorie) FROM tk25_9_poly

WARNING: Error while executing: "SELECT min(categorie), max(categorie)
FROM tk25_9_poly"

Is this not (yet) supported or something else wrong?!

Using psql the same syntax works.

Can somebody point me to the right direction?

Thank you

Stephan Holl
