Hi,
the reason for the different behavior is that the old QGIS version was
using GDAL to access PG rasters while the new versions uses a QGIS native
data provider which is using ST_SummaryStatsAgg() to calculate statistics,
I believe that this call can become very slow on large rasters and we
Dear QGIS-Developer
I am working on a test-server (RAID6) implementing PostgreSQL/PostGIS with
vector and raster support. The aim is a big database sharing different data
types including high resolution (0.5m, also 0.1m; 8 bit; 3 bands) rasters and
(2m, also 0.5m; 32bit floating point; 1 band)
Dear Developers,
I am using QGIS 2.2 .0 (Valmiera) and trying to load a raster query result
via DBManager, using the following query:
select 1 as rid, st_union(st_band(rast, '4,3,2') ) as rast
from o_8_lc81970232013202lgn00_all_rds_sub, gemeentegebieden
where gemeentegebieden.wkb_geometry rast

AFAIK it does not *require* it, but it is ture that without it it gives
lots of trouble.
Unfortunately gdal1.8 is not yet available on debian (not even in
experimental).
All the best.

You are right. You are referring to the plugin, I suppose.

Hi all.
More tests, now I cannot load a raster created with:
python raster2pgsql.py -r w001001.adf -t dtm_rt2 -l 1 -k 64x64 -o
dtm_rt.sql -s 3003 -I -M
or
python raster2pgsql.py -r utm.tif -t utm -l 1 -k 64x64 -o utm.sql -s
26711 -I -M
anmd severa other tests, but I always get:
ERROR 1: Can't
Hi Paolo,
Merry Christimas!
Ok, I'm going to implement the two sugestions:
1- Avoiding gdal 1.6 crash
2- Refresh on startup
But I don't know what you meant with the last mail. You mean by clicking the
row number?
Best regards,
Mauricio

Hi all.
Starting afresh with a new machine, with gdal 1.7, pg9.0 and postgis
svn, I have loaded the sample utm raster into qgis, but opening the
plugin I do not see any available raster. The tables are there.
Anything specific to check?
All the best.
