Dear Pietro,
I ran the same command with the highest level of verbose.
Unfortunately it didn't give much more information when

Hi Moritz - the SQLite DB seems to be inheriting the schema from the previous
PG driver? Even if I db.dropdb…. I don’t encounter this if I create a new
location… e.g. test
GRASS 7.0.0svn (nodeclean):~ db.dropdb
database='/var/tmp/nodeclean/PERMANENT/sqlite/sqlite.db'
GRASS 7.0.0svn
I wonder if there is any idea/intention to built in kind of a check
mechanism for modules applicable to raster data. This, and the Εxtent
concept as well, are most frequent problems/inattentions.

Can you set schema='' or something like that ?

Thanks Moritz - good suggestion - I just need to these as deliverables out to

The slow rate of writing out the v.net.allpair results from
PostgreSQL was due to the sheer volume of

I’ve encountered a bottleneck somewhere with v.net when scaling out with GNU

the batch jobs?
I’ve got 32 CPUs and commensurate RAM. What I’m observing is v.net CPU

Hi Mark,
Don`t know if that is of any help, but:
Have you tried the igraph package for very customized / sophisticated network
analysis (http://igraph.org/redirect.html)?
It plays nicely with R, python, and C and therefor also with GRASS.
What I did (now in several cases) is to use v.net and

GRASS is not doing anything like that. The computation region is always set

Haven’t come across anything to that effect
Can you set schema='' or something like that ?

I’ve reverted back to using solely PG driver - notwithstanding this SQLite
issue.
As a prologue to the several issues I encountered with Grass over the last few
days…
