If we start walreceiver with identify_system.xlogpos() we will have race condition with postgres start: postgres may request page that was modified with lsn smaller than identify_system.xlogpos(). Current procedure for starting postgres will anyway be changed to something different like having 'initdb' method on a pageserver (or importing some shared empty database snapshot), so for now I just put start of first segment which seems to be a valid record and is strictly before first lsn records.
