AFAIK it works fine. Shut down postmaster, move tablespace's directory tree somewhere else, fix the symbolic link in $PGDATA/pg_tblspc, start postmaster, update the pg_tablespace entry. There isn't anyplace else in Postgres that knows where that link leads. But if you are running a hot PITR backup, see the caveats in TFM about what will happen on the backup machine. > He might also want to initdb and populate a test cluster and practice > the procedure before doing it for real.
