Обсуждение: How to tell how long server has been up?

Maybe I'm blind (wouldn't be the first time), but I can't see a way to find out how long postgres has been running.  Is there a way to tell this from a query?  I am working with some of the stat views and would like to correlate them to how long the server has been running.

Thanks,

Chris

I can think of a couple of ways...

ps aux|grep postmaster

ls -l postmaster.pid
