• asyncpg version: 0.29.0
• PostgreSQL version: PostgreSQL 14.11 (Homebrew) on aarch64-apple-darwin23.2.0, compiled by Apple clang version 15.0.0 (clang-1500.1.0.2.5), 64-bit
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce the issue with a local PostgreSQL install?: NA
• Python version: 3.12.2
• Platform: MacOS M1
• Do you use pgbouncer?: NO
• Did you install asyncpg with pip?: rye/uv also tried with pip - same result
• If you built asyncpg locally, which version of Cython did you use?: NA
• Can the issue be reproduced under both asyncio and uvloop?: yes

I'm seeing this quite often when using a pool, I've checked the code, but can't imagine where it's coming from:

Exception ignored in: <function Connection.__del__ at 0x113f9dee0>
Traceback (most recent call last):
  File "/Users/samuel/code/logfire-demo/.venv/lib/python3.12/site-packages/asyncpg/connection.py", line 124, in __del__
    if not self.is_closed() and self._protocol is not None:
           ^^^^^^^^^^^^^^^^
  File "/Users/samuel/code/logfire-demo/.venv/lib/python3.12/site-packages/asyncpg/connection.py", line 1455, in is_closed
    return self._aborted or not self._protocol.is_connected()
           ^^^^^^^^^^^^^
AttributeError: 'Connection' object has no attribute '_aborted'

As far as I can tell I'm not doing anything different from normal usage of create_pool, I'm afraid the code isn't currently open source.

It's something weird we're doing, I'll close but if we get more information, we'll add details here.
