was that a file backup of the $PGDATA directory, or a database dump ?

you CANT start streaming replication with a database dump, as its not
the same timeline.  you have to use a file system level backup.

quite frankly, dealing with a production database this large, I do
believe I am going to recommend you bring an experienced postgresql
consultant on board who's dealt extensively with large scale
replication, someone like 2ndQuadrant, or CommandPrompt, or PGExperts,
etc, and let them advise you.
