[Fwd: broken db.dropcolumn in grass_trunk?]

[Nikos Alexandris]

(
did the forwarded message reach the grass-dev list?
)

Currently "db.dropcolumn" in "grass_trunk/scripts/db.dropcolumn"
complains:

-%<--
Traceback (most recent call last):
  File
"/geo/osgeo/src/grass_trunk/dist.x86_64-unknown-linux-gnu/scripts/db.dropcolumn", line 117, in <module>

    cols = [f[0] for f in grass.db_describe()['cols']]
TypeError: db_describe() takes exactly 1 argument (0 given)
-%<--

Shouldn't the "grass.db_describe()" [2] command fed with an argument
(e.g. the "table" string [1])? Not sure though since I am very beginner
with Python.

yes, see [1].
