It's not timing out in a matter of seconds, it just appears that DBD::Pg->ping is not sufficient as a keepalive. I'd estimate that I'm seeing a 5 minute timeout, but I haven't done any testing specifically aimed at verifying that.

The race condition I'm talking about (assuming a 5 minute timeout) is that the ping could run 4 minutes 59.999 seconds after the last query (while everything is still fine), the connection times out at 5 minutes, and then the next query (tries to) run at 5 minutes and 0.001 seconds after the previous one. eval is indeed the only way to catch that scenario and recover from it, but an ounce of prevention and all that.
