Multiple failures are not a big deal for me, but the connection pool doesn't seem to detect broken connections. It keeps failing hours after the 'service postgresql restart' was done.
I'll do some more tests here and look at the pool.py code as you suggested.
Daniele, thank you for the quick answer!
