Suppose, hypothetically of course, someone lacked foresight, and put a tablespace somewhere with a dumb name, like "/disk2", instead of using a symbolic link with a more descriptive name. And then /disk2 needs to be renamed, say to "/postgres_data", and this (hypothetical) DBA realizes he has made a dumb mistake.
Is there a way to move a tablespace to a new location without a dump/restore? I, er, this hypothetical guy, knows he can move it and put a symbolic link in for /disk2, but this is somewhat unsatisfactory since "/disk2" would have to exist forever.
Thanks,
Craig
