AFAIK, there aren't any audited public benchmarks for PostgreSQL. So,
you're not going to find a TPC-C or TPC-E for PostgreSQL yet. There
may have been one of the SPEC benchmarks that used PostgreSQL, but
that wouldn't have been direct OLTP.

Being free, PostgreSQL's cost-per-transaction would be fairly low.
Basically, if you purchase maintenance, support, installation, or
tuning services from a PostgreSQL support organization or consultant,
then you're cost/transaction is really based on that fee and the
number of your applications transactions run over the lifetime of the
support contract.

Unlike other database vendors, there's no cost/transaction for free PostgreSQL.
