> fsync=off
synchronous_commits=off replaced fsync=off in almost every use case
where fsync=off might have been useful. The only remaining use case is
for the initial build of a database. In that case what the user really
wants is to turn off WAL logging entirely though. Having a WAL log and
not fsyncing it is kind of pointless. I guess it lets you replicate
the database but it doesn't let you use the WAL log for recovery
locally.

A nice view that exposes a summary of information from the fsm per
table would be pretty handy.
In general there's a lot of data tied up in things like the fsm that
could be usefully exposed to users.
