Any more details?

Does a normal regress run take roughly that long? Or is the problem that the
027_stream_regress.pl ends up defaulting to shared_buffers=1MB, causing lots
of unnecessary IO?

One thing we could do to speed up the overall runtime would be to move
027_stream_regress.pl to something numbered earlier. Combined with
PROVE_FLAGS=-j2 that could at least run them in parallel with the rest of the
recovery tests.
