For some context

25G < PLC postgres < 100G, depending if you want to keep all the spam operations (> 50%) and/or add extra indexes for a handle autocomplete service (like me, takes it over 100GB with everything)

Repo data (records) is in the double digit TB range (low end, without any indexing, just raw)

Blobs are in the Petabyte range.

I aim to find out current and accurate details soon.
