Re: Session Identifiers

Tom,

I understand the idea that for external communication you rely on SSL.
However, how about me opening psql prompt into the database directly from
my Linux box, my db is installed at? I thought, it would be considered
local connection and would not go through the SSL channels. If that is the
case, here we would be dealing with Session IDs belonging to DB itself, not
OpenSSL.

Please, correct me if I'm wrong.

Thanks,

Oleg
