Traceback (most recent call last):

Due to internal query call:
SELECT pg_advisory_unlock_all ( ) CLOSE ALL UNLISTEN * RESET ALL

Happening quite frequently

Commencez par le point d’entrée de la traceback dans asyncpg/protocol/protocol.pyx et par la séquence de requêtes interne contenant SELECT pg_advisory_unlock_all(), CLOSE ALL, UNLISTEN * et RESET ALL. Reproduisez le timeout signalé avec asyncpg 0.25.0 et PostgreSQL 12.11, puis déterminez le comportement attendu et vérifiez que le nettoyage des verrous advisory n’expire plus.
