asyncpg.exceptions.UndefinedFunctionError: function pg_listening_channels() does not exist

this is error message

HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

and this is my python3.6 code

import asyncpg
import asyncio
import traceback


dsn  = 'postgres://gpadmin:gpadmin@172.16.16.134:2345/algo'

async def run_query(query):

    pool = await asyncpg.create_pool(dsn, command_timeout=60)
    con = await pool.acquire()

    try:
        if query.startswith('delete from') or query.startswith('insert'):
            result = await con.execute(query)
        else:
            result = await con.fetchval(query)
    except:
        print('Could not complete query "{}"'.format(query))
        print(traceback.format_exc())
        result = None
        exit(1)
    finally:
        await pool.release(con)
    return result


if __name__ == '__main__':
    
    loop = asyncio.get_event_loop()
    loop.run_until_complete(run_query('SELECT 1'))

Please tell me what can i do next

Beginne mit dem Traceback in asyncpg/pool.py:204-214 und connection.py:1115 und reproduziere anschließend das SELECT 1-Beispiel gegen den gemeldeten PostgreSQL-kompatiblen Server. Als erledigt gilt die Aufgabe, wenn festgestellt wurde, warum pg_listening_channels() während der Pool-Freigabe nicht verfügbar ist, und entweder ein Fix auf Repository-Ebene oder eine dokumentierte Kompatibilitätseinschränkung identifiziert wurde; das Issue nennt keinen Repository-Test und keine Zieldatei.
