No, I am not using SSL; it is either disabled or the default setting
is off anyway. This was one of the first things I have checked.
Moreover, this would probably make it hard to explain why does it take
no time to establish connections immediately after PostgreSQL restart
and why it does it degrade later.

To respond to previous emails - we tried doing DNS lookups against the
client host and they took no time.

Thanks for your ideas.
