我有一个postgresql远程数据库，其中所有postgis和光栅功能都已启用。
我正在尝试对方案中的栅格表执行查询，但系统返回以下错误

rt_raster_to_gdal: Could not load the output GDAL driver

通过使用以下代码

import psycopg2
from rasterio.io import MemoryFile
import rioxarray as riox
    
# DB Configuration
dbname = "Database"
dbuser = "user"
dbpass = "pass"
dbhost = "host.com"
dbport = "8080"

try:
    conn = psycopg2.connect(database=dbname, user=dbuser, password=dbpass, host=dbhost, port=dbport)
    curs = conn.cursor()
    print("Database connected successfully")
except:
    print("Database not connected successfully")
curs.execute("select ST_AsGDALRaster(st_union(rast), 'GTIFF') from schema.table;")
result = curs.fetchone()

我也尝试添加以下代码到previouse脚本，但没有什么变化

curs.execute("SET postgis.gdal_enabled_drivers = 'ENABLE_ALL';")

如何解决这个问题？
