I think this patch would simplift the patch to pass a connection string 
to pg_basebackup and pg_receivexlog: 
http://www.postgresql.org/message-id/005501cdfa45$6b0eec80$412cc580$@kommi@huawei.com. 
I note that pg_dumpall also has a similar issue as pg_basebackup and 
pg_receivexlog; there's no way to pass a connection string to it either.

If you could come up with a unified patch that takes care of all of 
those, that would be great.
