Hello,
since a few days I am back on the GRASS-Postgresql issue, this time using
GRASS 6, Postgis, Postgresql 7.4 (deb repository), however I am stumbling
over a few problems:
so far I did:
install GRASS
install Postgresql 7.4.7
> createuser
> createdb grass_pg
install PostGIS (deb unstable)
> createlang plpgsql grass_pg
inside GRASS
>db.login driver=pg database=grass_pg
> db.connect driver=pg database=grass_pg
>v.db.connect map=soils driver=pg database=grass_pg table=test_tb key=cat
layer=1 -o
>GRASS_INFO_WARNING(6534,1): Table <test_tb> does not exist in database
<grass_pg>
>GRASS_INFO_WARNING(6534,2): The table <test_tb> is now part of vector map
<soils2> and may be deleted or overwritten by GRASS modules.
>v.to.db map=soils2 type=point,line,boundary,centroid layer=1 qlayer=1
option=cat units=meters
DBMI-Postgres driver error:
Cannot select:
SELECT cat FROM test_tb
ERROR: relation "test_tb" does not exist
Updating database ... Segmentation fault
which point did I miss?
However I would love to have a tutorial how to use GRASS in conjunction with
Postgresql which tells me which software I do need and how I initialise this
cross-package functionality. I haven't found a link to a tutorial, in case I
missed it, I would be glad if you can send a link.
regards, Martin
