pg_renamecluster version oldname newname
pg_renamecluster changes the name of a PostgreSQL cluster, i. e. the name of the config directory in /etc/postgresql/version/ along with the data directory in /var/lib/postgresql/version/. Existing log files in /var/log/postgresql/ are also renamed. The cluster is stopped and started for the operation.
The following postgresql.conf config options are updated to refer to the changed path names: data_directory, hba_file, ident_file, external_pid_file, stats_temp_directory.
Cluster names are a Debian convention, the name is not explicitly known to the cluster itself. From the PostgreSQL viewpoint, the name is merely a substring of various path names.
