You can run python or perl on the server. That's what Jim meant with 'If
you're *that* concerned about performance than plpgsql probably isn't the
right answer anyway.'
Additionally: Many moons ago I did extensive and aggressive performance
analysis on a system that did many recursive queries. This was before CTEs
(WITH statements) and we settled on recursive plpgsql functions. The queries
in the functions were trivial, but nevertheless the bottleneck was in the
query and data processing, and never in the surrounding infrastructure.
