Have you considered setting up a synchronously replicated slave database on the new file system (using a port other than 5432), getting it in sync, then shutting both databases down (master first), switching the slave over to become the master and restarting just that database on port 5432? --

How do I migrate my 9.1 directory to a new file system with the least downtime possible?
I don't know if this makes any difference, but my pg_xlog directory is on its own volume as well, so I would have to unmount it and remount it as well, but I would not have to copy over my xlogs.
I figure the first part of this is to do a pg_start_backup() and rsync the files over., bu I'm not sure what to do after that.
Thanks for your help.
