Does anyone know of some resource that talks about doing this?
I'd recommand having a look at tsung which will be able to replay
a typical application scenario with as many concurrent users as
you want to:
http://archives.postgresql.org/pgsql-admin/2008-12/msg00032.php
  http://tsung.erlang-projects.org/
  http://pgfouine.projects.postgresql.org/tsung.html

If you want to replay your logs at the current production speed
and
concurrency, see Playr.
