Which PostgreSQL version are you planing to use for your tests?Sometime back, I have done the performance test for read-write pgbenchon Power8 m/c and came to know that scalability is not good.I am interested to see your tests results especially of HammerDB.
I was working with IBM Machines
on some benchmarks and it seamed
one would need IBM's compiler for Power Platform for more optimal code compilation for Power platform.
I had tried to compile the Postgres code using the same but had not
been successful because some dependencies.The benchmarks I did were using HammerDB and I too had not got very encouraging results. But that was on Power 7 and an older version of Postgres (9.2). Power 8 is supposed to be much more efficient.

We had tried some Linux and PowerVM level optimizations which had helped in general.
I would be interested to see how your tests come out.
