If not, and you have one near, what would be the size of it for the Mainnet?
https://howbigisalgorand.com/ indicates the size of all the databases together.
Today MainNet is: 495GB according to
SELECT pg_size_pretty( pg_database_size('mainnet'));
pg_dump may compress things and may be shorter.
What about this 1:100 ratio from the Indexer README?
As of April 2020, storing all the raw blocks is about 100 GB and the PostgreSQL database of transactions and accounts is about 1 GB. Much of that size difference is the Indexer ignoring cryptographic signature data; relying on
algodto validate blocks. Dropping that, the Indexer can focus on the ‘what happened’ details of transactions and accounts
Number of transactions significantly increased on Algorand starting May 2020.
See Algorand Stats, tab “transactions”
