+-- Fix geometry column type in tb_map_sheet_learn_data_geom table
+-- The table was incorrectly created with 'bytea' type instead of 'geometry' type
+
+-- 1. First ensure PostGIS is enabled
+CREATE EXTENSION IF NOT EXISTS postgis;
+
+-- 2. Clear existing data since it's in incorrect format (JTS serialized objects)
+-- This data needs to be reprocessed anyway with the correct PostGIS approach
+DELETE FROM public.tb_map_sheet_learn_data_geom;
+
+-- 3. Drop and recreate the geom column with correct PostGIS geometry type
+ALTER TABLE public.tb_map_sheet_learn_data_geom DROP COLUMN IF EXISTS geom;
+ALTER TABLE public.tb_map_sheet_learn_data_geom ADD COLUMN geom geometry(Polygon, 5186);
+
+-- 4. Create spatial index for performance
+CREATE INDEX IF NOT EXISTS idx_tb_map_sheet_learn_data_geom_spatial 
+ON public.tb_map_sheet_learn_data_geom USING GIST (geom);
+
+-- 5. Update column comment
+COMMENT ON COLUMN public.tb_map_sheet_learn_data_geom.geom IS 'PostGIS geometry 정보 (Polygon, EPSG:5186)';
+
+-- 6. Verify the column type is correct
+SELECT column_name, data_type, udt_name 
+FROM information_schema.columns 
+WHERE table_name = 'tb_map_sheet_learn_data_geom' AND column_name = 'geom';
