Out of curiosity, can anyone share his tips & tricks to validate a machine before labelling it as 'ready to use postgres - you probably won't trash my data today' ?
Write a little script that runs pgbench in a loop forever. Set your shared_buffer cache to use at least 50% of the memory in the machine, and adjust the database size and concurrent clients so it's generating a substantial amount of disk I/O and using a fair amount of the CPU.
Install the script so that it executes on system startup, like adding it to rc.local Put the machine close to your desk. Every time you walk by it, kill the power and then start it back up. This will give you a mix of long overnight runs with no interruption to stress the overall system, with a nice dose of recovery trauma. Skim the Postgres and OS log files every day. Do that for a week, if it's still running your data should be safe under real conditions.
