I am running Postgres 9.1
I have followed the howto here:
http://wiki.postgresql.org/wiki/Streaming_Replication
I am attempting to replicate an existing database.
On the Master, I get the following error in the postgres log file:
FATAL:  must be replication role to start walsender
On the slave I get this:
FATAL:  could not connect to the primary server: FATAL:  must be 
replication role to start walsender
I have googled both of those log entries to no avail.
note that the sender process on the master is not running.
What simple step am I missing?
