Hi Jim
I suspect the source of the problem is the commented-out line
-- ST_FromGDALRaster(pg_read_binary_file(%s)),
in the statement.
You are right. I was not expecting the comment to be relevant for the
parameter replacement. Many thanks for the hint.
That is an SQL(---) comment and I am guessing the parser sees the
parameter before it gets to the comment.
I now have an error, not related to psycopg, as far as I can tell.
psycopg2.errors.InternalError_: RASTER_fromGDALRaster: Could not open
bytea with GDAL. Check that the bytea is of a GDAL supported format
This looks to be on the PostGIS end related to the ST_FromGDALRaster()
function. Does:
select ST_FromGDALRaster(the_field);
work in psql?
Maybe the difference in the errors is due to a different version of
psycopg? This is what I am using:
sys.version
'3.12.3 (main, Sep 11 2024, 14:17:37) [GCC 13.2.0]'
>>> psycopg.__version__
'3.2.3'
Probably.
sys.version
'3.11.2 (main, Aug 26 2024, 07:20:54) [GCC 12.2.0]'
psycopg.__version__
'3.1.7'
Many thanks for your support.
