This list contains all known PostgreSQL bugs and feature requests. If
from the template database, it is not clear that setting schemas to the db
owner is correct.
-* Add function to report the time of the most recent server reload
-* Allow statistics collector information to be pulled from the collector
- process directly, rather than requiring the collector to write a
- filesystem file twice a second?
-* Reduce file system activity overhead of statistics file pgstat.stat

address.
