Hi Even,

just to conclude :-)
Yes, you were right (as usual !):
Using "gdalbuildvrt -addalpha" along with "gdal_translate -co
TILING_SCHEME=xxx" does the job.

I just needed to be *very* patient:
1) gdal_translate takes a long time: more than an hour.
Without "-co TILING_SCHEME=xxx" option, it takes less than 30 seconds
2) there is a temporary xx.db file which grows a lot (up to 15 GB)
3) by the end, my GPKG file is less than 1MB and all the temporary files are
destroyed.

So far so good, although my use-case is not very efficient.
