Right. The remaining cases would be fairly much those where the 
configuration is such that a connection is not possible. My feeling is 
that if people tie themselves down that tightly then they should also 
specify "no wait" with pg_ctl - it depends on how much we want to keep 
backwards compatibility with this behaviour.
