[postgis-users] out db: not able to query the raster

[andy]

Hi all,
I had missed some messages, sorry.
But I still can't do a query on a raster.

I'll rewrite everything I've done.

I start with docker:

docker pull postgis/postgis:16-master

docker run --name postgis16 \
-p 5432:5432 \
-v /home/user/folder:/directory_docker \
-e POSTGRES_PASSWORD=thePassword \
-d postgis/postgis:16-master

Then I run

docker exec -it postgis16 bash

If I run "ls /directory_docker/" I get "ou_s6_01_01_stack.tif"

If I run "SELECT * FROM pg_ls_dir('/directory_docker');" I get
"ou_s6_01_01_stack.tif"

Then I load this tif in postgres

raster2pgsql -I -C -M -F -t auto -R /directory_docker/ou_s6_01_01_stack.tif
public.nome_tabella | psql -U postgres -d postgres

If I run

select * from nome_tabella limit 1;

I get something like

rid,rast,filename
1,01000....,ou_s6_01_01_stack.tif

Something that is strange for me is that there is no path, only the
filename.

At the end I run "SELECT ST_Value(rast, 1, 1) FROM nome_tabella;" and I get

ERROR:  rt_band_load_offline_data: Cannot open offline raster:
/directory_docker/ou_s6_01_01_stack.tif

Then I copy my tif in /var/lib/postgresql/data and I import it again using
raster2pgsql.

I have again

ERROR:  rt_band_load_offline_data: Cannot open offline raster:
/var/lib/postgresql/data/ou_s6_01_01_stack.tif


I'm sorry I'm boring you, it should be an immediate thing, I can't
understand what the problem might be.

Thank you (below my tif metadata),

Andrea
