insufficient data in buffer

Comienza con las entradas del traceback en asyncpg/protocol/coreproto.pyx, asyncpg/protocol/codecs/float.pyx y asyncpg/protocol/frb.pyx; después, revisa la ruta de ejecución asíncrona de SQLAlchemy que se muestra. Reproduce el fallo con las versiones indicadas de Python, PostgreSQL y asyncpg y determina si se puede aislar el búfer truncado. Se considerará terminado cuando haya una causa confirmada y una prueba de regresión o una reproducción claramente documentada.

• asyncpg version: 0.29.0
• PostgreSQL version: 15.6
• Python version: 3.11.4
• Platform: debian
• Do you use pgbouncer?: no
• Did you install asyncpg with pip?: yes
• Can the issue be reproduced under both asyncio and
  uvloop?: not sure

is it a network issue or somewhere I need to look into?
