Not using transactions but receiving errors with: Resetting connection with an active transaction

Il traceback punta a asyncpg/connection.py in reset e a asyncpg/pool.py in release dopo che connection.execute fallisce su un INSERT per un duplicate key. Inizia riproducendo la sequenza pool acquire, INSERT fallito e release con la configurazione PostgreSQL riportata; il lavoro è completato quando si determina perché reset invia ROLLBACK e si documenta o testa la gestione prevista.

• asyncpg version: 0.29.0
• PostgreSQL version: 15.6
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
  the issue with a local PostgreSQL install?: Local Postgres
• Python version: 3.11.8
• Platform: Linux
• Do you use pgbouncer?: No
• Did you install asyncpg with pip?: Yes
• Can the issue be reproduced under both asyncio and
  uvloop?: Yes

I'm using a connection pool and doing individual connection.execute however if there's any kind of error with the SQL I will get an error that asyncpg is trying to rollback the transaction.

I'm very specifically not trying to use transactions at all.

app.ctx.crate_pool = await asyncpg.create_pool(**CRATE_DB_CONFIG, loop=loop, max_size=10)

async with app.ctx.crate_pool.acquire() as connection:
    await connection.execute("INSERT INTO table1 (col1, col2, col3) values ($1, $2, $3)", var1, var2, var3)

If there's a conflict on the insert I will receive the following error:

Resetting connection with an active transaction <asyncpg.connection.Connection object at 0xffffa51cfc40>
