Define both "high" and "Postgres-powered".  Afilias's registries have always
run Postgres, and we've had for some time now hundreds of registrars, each
of whom have at least 5 connections (== 5 login sessions) at a time.  So
those systems frequently have thousands of concurrent users in one sense.

The whois servers also are backed by PostgreSQL, but they're of course
all-read activity.  Nevertheless, they're wide open to the Internet, so we
have had very large numbers of simultaneous connections sometimes.

Supporting data is included in various bid materials that have been
submitted to ICANN for delegations of (among others) .org, .net, and .mobi.
Those materials are archived on the ICANN site, and therefore accessible by
anyone on the Internet.
