In Conway era, at the first block of each epoch, DBSync uses finishDRepPulser to force the computation of the drep snapshots. It extractthe information it needs and stores it in the db. To avoid recomputing the drep pulser we can adjust the ledger state by replacing the newEpochStateDRepPulsingStateL with the computed version. ledger provides forceDRepPulsingState which can be used for this.
