This is a good place to start:

I would expect that the case studies for databases greater than 7TB are
few and far between (for any database software). If you decide
PostgreSQL is right, I'm sure the advocacy mailing list would like to
see your case study when you are finished.

Your hardware requirements mostly depend on how you're going to use the
data. If you expect that most of the data will never be read, and that
the database will be more of an archive, the requirements might be quite
reasonable. However, if or when you do need to search through that data,
expect it to take a long time.
