I am a fairly experienced Oracle DBA, and we are starting to move in to the PostgreSQL world. I would expect the standard monitoring items are required for mission critical postgres apps, Ie, disk space, wal log space, log monitoring, process counts,software running, connection available on the correct port, CPU usage.
