A database with about 115k bib records and nearly 800k items takes a
little under 5GB to store on disk, fully indexed with the default
configuration.  That doesn't include the Postgres WAL overhead
(configurable) or slack space that can build up in other more active
tables.

As a baseline, I would say you'd want about 4GB per 100k bibs, plus
500MB per million items, and the same again for patrons and circs.
YMMV, etc ... :)
