Sorry for the late reply.  I have been swamped with work this week and
haven't gotten to this until now.  (Development and preparing to
deliver PostgreSQL training in Malaysia.)

It's hard to know how many people are using LedgerSMB in production or
how many paying customers expist between Command Prompt and us.  I
would consider (as Ned does!) accounting and ERP to be mission
critical.

However, our largest customers are midsized businesses which limits
the size and scope of what you are talking about.  The largest is a
decent-sized financial services company.

We don't have any businesses deploying anything that big.  I think our
largest deployment is either 4 or 8 cores, and it performs very well
under a very complex load (the accounting app is web-based and so we
have to do some less than optimal things performance-wise to ensure
state of accounting access gets tracked correctly between sessions,
and yet PostgreSQL is rarely if ever the bottleneck).

I don't have anyone else to add to the list at present.
