It sounds like this data is not that valuable, so a small window of
data loss in the event of a crash might be acceptable for a gain in
performance. If that is the case, consider turning off
synchronous_commit. Note that this is something that you can do at the
transaction granularity, so, for example, if there are financial
transactions, they need not make this trade-off.
