[ADMIN] after failover?

[Ray Stell]

The tutorial here excludes an important issue:
http://wiki.postgresql.org/wiki/Binary_Replication_Tutorial#Failing_Over_To_The_Standby
After the failover is complete, it seems like a restart is required to
make the new primary capable of supporting a new hot standby. Can the
config values be changed without an interuption of service? I'm using
a hotstandby config in 9.0.x. Anything different in this regard in 9.1?
Thanks.

There's no reason not to have wal_level = hot_standby on the standby also.
