# Kill idle-in-transaction connections after 5 min to prevent autovacuum blocking.

# Without this, abandoned transactions (e.g. forgotten shell sessions) hold back vacuum,

# causing dead tuple buildup on hot tables like django_celery_beat_periodictasks.

# This led to a 2-day autovacuum lock on a single-page table, freezing pg_dump and celery beat.
