Fujitsu has (had?) a noteworthy derivative as well. IIRC, they
bolted the front end of postgres to their ESM storage engine.

The fact that a large (bigger than Oracle) company like Fujitsu
supported postgres (both their own fork and the normal one as well)
was useful to me a couple times on convincing companies that Postgres
was a serious product worthy of consideration with the big vendors.
