At the time it sets max_connections there is no server to test against. 
initdb in fact never uses a standard client connection at all, and never 
starts postmaster. To do a check on max_connections you would have to 
start postmaster and then try to start that many client connections. 
That's a lot of extra lifting to put into initdb for what is arguably at 
worst a rare problem.
