我正在創建試圖從Python中創建Postgres中的函數。我與postgres數據庫的連接使用Psycopg 2,並在其他情況下成功連接。代碼:在Python中創建Postgres函數
pg_cursor.execute('CREATE OR REPLACE FUNCTION %s.fix_geometry(geometry) \
RETURNS SETOF geometry AS\
$BODY$\
SELECT geom the_geom\
FROM \
(\
SELECT (st_dump(st_buffer(st_snaptogrid(st_makevalid(the_geom), 0.5), 0))).geom\
FROM (SELECT geom the_geom FROM st_dump(st_snaptogrid($1, 0.5))) a\
) b\
WHERE geometrytype(geom) = \'POLYGON\' AND st_area(geom) >= 0.01;\
$BODY$\
LANGUAGE sql VOLATILE\
COST 100\
ROWS 1000;' %(schema)) #line 84
pg_connection.commit()
pg_cursor.execute('ALTER FUNCTION %s.fix_geometry(geometry) OWNER TO analysis' % (schema))
pg_connection.commit()
我得到一個錯誤:
line 84, in
ROWS 1000;' %(schema))
ProgrammingError: type geometry does not exist
當我運行在pgAdmin的它的代碼執行成功。我錯過了什麼?
