postgresql fsync's all its files before returning from a commit in order
to ensure durability, right?  Does softupdates interfere with the
functioning of sync(2)/fsync(2)?

I recently decided to take up the issue of migrating towards 5.1 at my
company.  The way I dealt with it was to publish all of my services to 5.1
boxes and run regression tests.  For me, 5.1 provided adequate
performance, and since 5.1 is on the branch where all new dev work is
going on and 4.x is going to be end-of-lifed in the not-too-distant
future, I decided to go with 5.1.

Personally, I would only go with 4.8 if testing showed 5.1 to be
inadequate for your particular situation with your particular apps,
hardware, load, etc.  But you can only tell that by testing.
