Yep, symlinks are the way at present (though I think someone is working on 
tablespace support). The files are named after the OID of the object they 
represent - there is a useful oid2name utility in the contrib/ folder.

You might want to check the archives though, and see what RAID setups people 
prefer - less trouble to maintain than symlinking.
