If Google's TCP connections time out, naturally your Postfix server will
have no record of the connection attempt, and your Postfix configuration
plays no role in the problem. This is a transport or network layer issue,
and nothing at the application level will fix it.
For what it's worth, I have no issues connecting:

Perhaps your server's connection smtpd(8) process limit is exhausted
from time to time, but Google's email should get through eventually,
unless there is a systemic network level issue.
