Postgres on Ubuntu Replication Issue

I feel I may be missing something but I had been using the following repo:

https://github.com/Azure/azure-quickstart-templates/tree/master/postgresql-on-ubuntu

I followed all the instructions but couldn't get streaming replication working. It took me a few days as i expected it was something I was doing wrong with permissions but it _seems_ that you do not set the data directory after you have done all your configuration in setup_datadisks.

As soon as I set the data_directory in postgressql.conf in /etc/postgresql/9.3/main to point at the new data directory (data_directory = '/var/lib/kafkadir/main') it all started working.

However, this feels very basic as it simply wouldn't work without this being set so i can't believe I am the first to find it .... is this really a bug or have i done something that would have caused this not to work?

thanks,
steven

Inspect the postgresql-on-ubuntu template, starting with setup_datadisks and the PostgreSQL configuration at /etc/postgresql/9.3/main/postgresql.conf. Reproduce the deployment and check whether data_directory is configured for the new data directory. Done means streaming replication works without the reported manual change, or the required configuration is clearly documented.
