We have a puppet script that helps with server deployment (no puppet master). We would like to add the following things alongside our postgresql module:
1) pg_bouncer (http://pgfoundry.org/projects/pgbouncer)
2) continuous archiving (http://www.postgresql.org/docs/9.1/static/continuous-archiving.html)
Let me know if you can help. This is meant as a fixed-price project, but there is room for further collaboration down the line.
