Why don't you use the official way to re-configure the Windows service and use pg_ctl unregister and pg_ctl register to make it use the correct data directory. There is no need to manually change the registry. > I am unable to rename \data to move all my old files wholesale into that folder, as Windows won’t let me, > but if I move \base which appears to have all the database in it (and is about double the size in my old dataset), > I get the same result, I can’t see my tables. I you can't move the directory it means it is still be used/locked by another process. I always use ProcessExplorer (or ProcessExplorer, both from www.sysinternals.com - now Microsoft) to be indispensable to figure out which process is locking a file. > I realise Thomas at least will frown most deeply at these ‘operations’, though they often work as a low-tech solution in many programs. I do change the registry manually myself that's not the point. But I only do it if there is no tool support for it. Changing the windows service is much easier done through pg_ctl and ensures that nothing is forgotten.
