Why? No one has suggested that the same timeout must be applied to
every connection. Clients that are going to do maintenance stuff like
VACUUM could just disable the timeout.
This does bring up thoughts of whether the timeout needs to be a
protected variable (SUSET or higher). I'd argue not, since a
noncooperative client can certainly cause performance issues aplenty
no matter what you try to impose with timeouts.
