[GRASS-user] v.buffer database error

[Falko Engel]

Dear list,

I had a strange behavior of v.buffer today:

v.buffer input=mydata output=mydata_buf bufcolumn=my_buf_col

results in an error:

"DBMI-Postgres driver error:
Cannot select:
SELECT cat, my_buf_col FROM mydata"


However, if I copy the exact statement of the error message into

echo "SELECT cat, my_buf_col FROM mydata" | db.select

the result is fine!


Any ideas?



I'm using the following setup:
Opensuse 11.3, GRASS GIS 6.4.2

My attribute tables are stored in a Postgres DB which is located on a 
network server.
All other DB operations in GRASS are fine.
