Hmm, that's a bit tricky, since I assume you're using a local db
connection inside the tunnel, so inet_server_addr() probably returns
null. If you're talking unix/linux machines, then /etc/hostname _should_
have the current hostname in it, so:

create temp table foo (t text);
copy foo from '/etc/hostname';
select * from foo;
drop table foo;

Should work.
