long term persistent tunnels

Now that I have ssh tunneling working I am wondering what pitfalls
away.

Assume I have a server called db1 running the postgresql backend.

Asume I have another server called web1 that will be connecting to db1
for data base operations.  If I setup an ssh tunnel should I be aware
of any problems with 1) spontaneously dropped connections...2) long
term time out -- 3)other?

any advice most appreciated.
