If this is PG 12.0 or 12.1, a likely theory is that this is an EvalPlanQual bug (which'd be triggered during concurrent updates of the same row in the table, so that squares with the observation that locking the table prevents it). The known bugs in that area require either before-row-update triggers on the table, or child tables (either partitioning or traditional inheritance). So I wonder what the schema of table "containers" looks like. Or you could have hit some new bug ... but there's not enough info here to diagnose. regards, tom lane
