Where I would have used a prewarm utility is following an off-hours
VACUUM FREEZE run.  Where this maintenance made sense the only
downside I saw was a brief period in the mornings where the cache
was not populated with the "hot" data, and performance was somewhat
degraded until the cache settled in again.

So, +1.
