> Partition pruning is important optimization for SQL queries. But in case partitions are calculated incorrectly, it may lead to query returning less data than expected. Possibility of such scenarios should be mitigated by excessive testing. But it will not give us bug-free guarantee.
> Let's add special flag which will disable partition pruning for specific user queries.
