In fact from the time when PostgreSQL support was added, some more
Erlang drivers have appeared and some of them covers the entire
protocol. So it should be possible to update Tsung to use them, given
some interest.

Yes, because you typically run the proxy only to record sessions, in
order to prepare the tsung setup. Another way to go from logs is to use
pgfouine, which knows how to prepare a tsung config from PostgreSQL
logs:

Well never use the tsung recorder in production. Ever. Run it to
construct your sessions files from your application.
