Hi,

I noticed from the GeoRaster driver that in GDAL 3.6 and 3.7 (maybe 3.8 too),  
there are two GDALOpen() calls on the driver with GDALOpenInfo eAccess as 
GA_ReadOnly, even when the GeoRaster is the output format in gdal_translate 
command. There are no such calls in GDAL 3.4. I am wondering if these 
invocations of Open() with eAccess as GA_ReadOnly are necessary when the driver 
is the output driver. This has caused performance issue for the GeoRaster 
driver when a user is trying to load the data into Oracle database because it 
has two unnecessary reads from the database.  If these Open() calls are 
unavoidable, how to differentiate the calls whether it is as input or as output 
in the gdal_translate command?

Thanks.
