We have a customer running PostgreSQL for years now since POWER5 and
PostgreSQL 8.2. There were problems in the beginning but they were mostly
related to storage. They used SLES10 at the beginning, which ran well, but
whoever tries to maintain such a system will have an idea how hard SuSE can
be...
They run now on POWER7 with RHEL6 for a year now without any bigger
problems (complete redesign of the setup and storage with IBM SVC). The
instances itself perform very well and i have to say that this setup is
very very mission critical for their setup. The whole strength of this
platform are the powerful virtualization capabilities and its performance
there, i think.
But i have to admit, you need some very experienced people to get the whole
stuff running.
