What version, configuration, hardware, do they use replication and how?

I just remember reading that the .org TLD was running on Postgres ten plus years ago. Yahoo knows a thing or two about scaling up on Postgres as well, as I recall. When these decisions were made, it was generally expected that one would have quite a lot of work to do, regardless.

Makes me wonder how much hacking of postgres source code it required.

Me to having worked for a registry ICANS requirements for up time and availability are "challenging"

Would be very interesting to see how they setup PostgreSQL to support HA
