将栅格数据加载到Postgres表时出错

Question

在将栅格数据加载到postgres表时出现错误

ERROR:  function st_bandmetadata(public.raster, integer[]) does not exist
LINE 1:  SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1...
                                                  ^

对此有任何想法吗？

我尝试创建表的数据库中存在以下扩展名：

CREATE EXTENSION postgis
CREATE EXTENSION postgis_topology
CREATE EXTENSION fuzzystrmatch

如果您有任何想法，请帮助我。

我为数据库设置的搜索路径是::

search_path                      
----------------------------------------------
 "$user", public, rasters, postgis, pg_catalog

post_GIS version

SELECT postgis_version();
            postgis_version            
---------------------------------------
 2.1 USE_GEOS=1 USE_PROJ=1 USE_STATS=1

如果您早些时候遇到过这个问题，请告诉我。
