[gdal-dev] postgis raster driver

Jachym,

https://gdal.org/drivers/raster/postgisraster.html should better reflect the 
current state.

This still holds true

> The write support to GDAL PostGIS Raster driver is under development

Not sure if it has really been in developmenet. Not to my knowledge at least.

> How much work is needed, to be able to use gdalwarp instead of raster2pgsql

It depends... PostGIS raster tables can be extremely deverse, from very 
loosely/non-constrainted (arbitrary resolution of 'patches', no tiling, etc), 
to super constrainted (tiling of tiles of same size and resolution). Updating 
/ creating a new raster table with the later (strictly constrainted) could 
perhaps be an effort of the order of one week for someone already familiar 
with GDAL & this driver in particular. I don't think writing in loosely/non-
constrainted tables would be reasonably doable.
