> If the incremental dump event sequence have ADD_PARTITION followed by ALTER_PARTITION
doesn't create any task for ALTER_PARTITION event as the partition doesn't exist during analyze
phase. Due to this REPL STATUS returns wrong last repl ID.
> Scenario:
> 1. Create DB
> 2. Create partitioned table.
> 3. Bootstrap dump and load
> 4. Insert into table to a dynamically created partition. - This insert generate ADD_PARTITION
and ALTER_PARTITION events.
> 5. Incremental dump and load.
> - Load will be successful.
> - But the last repl ID set was incorrect as ALTER_PARTITION event was never applied.
