Tom, thanks again for correcting the confusion and my lack of
knowledge in SSH tunneling.

OK, agreed, it is not wrong, but it is certainly not transparent
either. If I understand the things now, the documentation as is (-L
3333:foo.com:5432) works as long as
listen_addresses = '*' OR listen_addresses = 'a.b.c.d' (where a.b.c.d
is the IP of foo.com)
in postgresql.conf. Am I right? If so, is this obvious from the online
documentation? Unfortunately, it wasn't to me!

Precisely, that is the configuration: " listen_addresses = 'localhost'
".... In which case, " -L 3333:localhost:5432 " has to be used.
Shouldn't this be mentioned in the documentation? This whole thing is
not trivial!!!
