[GRASS-user] Problem to overwrite postgis layer with v.out.ogr

[Marcello Benigno]

Hi All,

I'm trying export a layer overwriting the table in PostGIS fortmat:

v.out.ogr -c input="bacia_usuario" type=area 'dsn=PG:host=localhost
dbname=gis user=marcello password=mypass' olayer=bacia_1 layer=1
format=PostgreSQL

but the prompt show the message:

ERROR 1: Layer bacia_1 already exists, CreateLayer failed.
Use the layer creation option OVERWRITE=YES to replace it.
ERROR: Unable to create OGR layer

So I tried using this commands, with no results:

v.out.ogr -c input="bacia_usuario" type=area 'dsn=PG:host=localhost
dbname=gis user=marcello password=mypass' olayer=bacia_1 layer=1
format=PostgreSQL *--overwrite*

v.out.ogr -c *OVERWRITE=YES* input="bacia_usuario" type=area
'dsn=PG:host=localhost dbname=gis user=marcello password=mypass'
olayer=bacia_1 layer=1 format=PostgreSQL

What is the correct way to do this?

Thanks in advance,
