There's a bunch of information on this topic at
http://wiki.postgresql.org/wiki/Category:Benchmarking ; the entries for
DBT-{2,3,5} are open source implementations of some of those. And the
links at the top there point to info about the sole audited PostgreSQL
benchmark I'm aware of, which is a SPEC result rather than a TPC one.

Official TPC results require spending a lot of money, from buying
servers to having the results audited, and there's very little value
received for that expense from the perspective of the PostgreSQL
community. The fact that the software is free doesn't quite fit into
the whole performance/$ focus of what real TPC results deliver. TPC-H
is the most interesting of them to me (and that's where there's a
detailed page linking to resources related to it) because it suggests
types of queries the database could handle better than it does right now.
