We have a group of Oracle and MS SQL Server DBAs who are looking to get a jump start on postgres. Would anyone here have recommendations for high-quality postgres training that focuses on administration (architecture, filesystem layout/optimization, install, configure, update/patching, backup and restore, user security, performancing tuning)? Most of the training that I have been able to find so far are more along the lines of "zero to hero", with a lot of focus on sql.
We are in Illinois, and I see that there is a Postgres user group in Chicago, but the website listed on the User Group community page seems defunct.
