The chain blocks table is extremely large, how do I make it smaller?

[gizmotangle]

I'm running a graph node on base with some deployed subgraphs. The blocks table in chain1 has now grown to over 2.5 TB. How can I shrink it? I've already performed a prune to 10 million blocks with graphman, but the blocks table is still extremely large. How do I free up memory?

Thanks for your answer @codebyankita .
I've already tried running a vacuum job on the blocks table. Unfortunately, it ran for several days and ultimately didn't really achieve anything. The actual subgraph tables are much smaller, so I was hoping there was another way to delete the blocks.

@gizmotangle did you find any improvements?

Is this an actual issue with code? It doesn't seem to be a bug
