A few off the top of my head:
Instagram had over 20TB of data in PostgreSQL at acquisition time per
their presentation; no doubt they have more, now.
Comptel's cell call tracking database for the EU had up to 75TB per city
for 20+ cities.
There's a marketing company in Australia which had over 200TB of data in
PostgreSQL -- I can't recall the name right now.
The Mormon Tabernacle's entire geneology database is in PostgreSQL; not
sure how big that is, but it covers over 200m individuals.
I don't know that anyone has petabytes on vanilla PostgreSQL; we don't
do well at that scale. GreenPlum, Aster, etc. yes, but not mainstream
Postgres. However, nobody has petabytes on mainstream Oracle either.
