Python / psycopg2：更新几何时解析错误

Question

我正在使用以下 SQL 代码更新包含几何图形的表，并使用 pgadmin 中的查询工具进行工作：

INSERT INTO mytable (id, geometry) VALUES (1, ST_SetSRID(ST_GeomFromText('Point(15.5 17.7)'),4326), < more tuples >
ON CONFLICT (id) DO UPDATE 
geometry = EXCLUDED.geometry

我想使用此代码使用 psycopg2 从 Python 进行批量更新插入。

# Mock code:
# Prepare geodataframe for upsert:
points = ["ST_SetSRID(ST_GeomFromText('Point({} {})', 4326)".format(geo.x, geo.y) for geo in gdf.geometry]
gdf = gdf.assign(points=points)

upsert_tuples = [tuple(x) for x in gdf[['points', 'id', <other relevant cols>]].to_numpy()]

# SQL code
upsert_sql =  '''INSERT INTO mytable (geometry, id, <other cols>) VALUES %s 
              ON CONFLICT (id) DO UPDATE SET
              geometry = EXCLUDED.geometry,
              <other = etc>;'''

# Connect to database
...
extras.execute_values(cursor, upsert_sql, upsert_tuples)
...

这会引发错误消息：

parse error - invalid geometry

。如何从 Python 更新插入几何图形？
