how to move a postgres tablespace on windows?

Now do I move a tablespace on a windows installation of postgres? This thread shows how to do it on unix, not windows. The tablespace was originally created with this command... CREATE TABLESPACE tabspace2 OWNER theowner LOCATION 'e:/pgdata2/fdb'; The command ALTER TABLESPACE allows the name to be edited, but I need to change the file location. Work from the previous thread, I can get the oid from SELECT oid,spcname FROM pg_tablespace WHERE spcname = 'tabspace2'; Digging through my postgres installation I've found this folder where the bottom level foldername matches the oid c:\pg_data\14\data\pg_tblspc\57620. The icon for this folder has a little blue arrow in the bottom left corner - indicating (I think) that the folder is a link. I believe that this links to the location on e: that was specified when the table space was created. The trail starts to run cold here, I think windows links can only be dropped or created (not edited), so how can I move the tablespace? It's currently populated with live data, so I'm trying to establish the correct methodology *before* I start fiddling. Any help appreciated.
