v.out.postgis doesn't export attribute table

[martin]

Attribute table has one column.
"v.out.ogr" creates a proper column in PostGIS accordingly, "v.out.postgis" doesn't.

This seems to be linked to the handling of feature types:

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o

gives me the full attribute table, while

v.out.postgis in=censusblk_swwake type=area output='PG:dbname=nc_grass' --o

only gives me fid, cat and geom columns.

BTW, when I try

v.out.postgis in=censusblk_swwake type=centroid output='PG:dbname=nc_grass' --o

I get

ATTENTION: Unsupported geometry type (8)
ATTENTION: Unable to write feature in vector map <censusblk_swwake>
ERREUR :Feature type 8 is not supported
Erreur de segmentation

Perhaps related: r62360 (reported in #2436)?

The following patch apparently "solves" the problem for me, but I don't know what consequences this might have, nor why it works as I don't get a fatal error anyhow...

Right, it's still issue and must be solved before closing this ticket.

Right, it's still issue and must be solved before closing this ticket.

Should be fixed in r70505.

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o type=point
-> nothing is exported

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o type=line
-> nothing is exported

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o type=centroid
-> centroids exported as points

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o type=boundary
-> boundaries exported as linestrings

v.out.postgis in=censusblk_swwake output='PG:dbname=nc_grass' --o type=area
-> areas exported as polygons

Testing welcome.
