[Bug] graphman truncate doesn't remove 300 GB of the old blocks from db

Bug report

When using graphman chain truncate I still see over 2.5 million blocks in chain4.blocks table and 5.5 million in chain5.blocks inside postgres. They are taking around 300 GB of space. Why are they not removed? Can I remove them in any other way? I don't see a reason why they are kept there.

Relevant log output

    table_schema NOT IN ('pg_catalog', 'information_schema')

Il report si concentra su graphman chain truncate e sulle tabelle PostgreSQL chain4.blocks e chain5.blocks. Inizia riproducendo il troncamento e verificando i conteggi delle righe, le dimensioni delle tabelle e le dimensioni TOAST riportati prima e dopo la sua esecuzione. Il lavoro è completato quando il comportamento del comando è spiegato e i vecchi blocchi vengono rimossi oppure viene identificato un percorso di pulizia documentato.
