Wouldn't it be a prerequisite here? I don't actually have any reason
to prefer the old function-based code to the new stored procedure
based code. Really, all I'm looking for is a credible implementation
of TPC-E that I can use to model some aspects of OLTP performance for
my own purposes.

TPC-C (which I have plenty of experience with) has only two secondary
indexes (in typical configurations), and doesn't really stress
concurrency control at all. Plus there are no low cardinality indexes
in TPC-C, while TPC-E has quite a few. Chances are high that I'd learn
something from TPC-E, which has all of these things -- I'm really
looking for bottlenecks, where Postgres does entirely the wrong thing.
It's especially interesting to me as somebody that focuses on B-Tree
indexing.
