Hello,

Andrew Gierth pointed out that I left behind some outdated advice
about RAID spindles in the GUC's extra description field, in commit
b09ff536.  Let's just drop that description.  Patch attached.

Commits

  1. Remove outdated reference to RAID spindles.

  2. Simplify the effective_io_concurrency setting.
