Hi
By default pg_createcluster will create a new cluster in /var/lib/postgresql/<version>/<cluster>
I wan't to move my data_directory from this location to another volume (with lots more space). Is it best practice to set the data_directory location --datadir with pg_createcluster, or to just move the data_directory contents to the new volume and then create a symbolic link (as postgres) from /var/lib/postgresql/<version>/ to the new volume? This seems to be essentially the same thing, but I wondered if there were any gotcha's with using symbolic links in this way (e.g. if we tried to run multiple clusters on one host), rather than specifying the data_directory at pg_createcluster time - which subsequently sets this parameter in the postgresql.conf?

Thanks in advance!
