Invoking pg_upgrade v14

When invoking pg_upgrade, you must specify the location of the old and new cluster's PGDATA and executable (/bin) directories, as well as the name of the EDB Postgres Advanced Server superuser, and the ports on which the installations are listening. A typical call to invoke pg_upgrade to migrate from EDB Postgres Advanced Server 13 to EDB Postgres Advanced Server 14 takes the form:

pg_upgrade
--old-datadir <path_to_13_data_directory>
--new-datadir <path_to_14_data_directory>
--user <superuser_name>
--old-bindir <path_to_13_bin_directory>
--new-bindir <path_to_14_bin_directory>
--old-port <13_port> --new-port <14_port>

Where:

--old-datadir path_to_13_data_directory

Use the --old-datadir option to specify the complete path to the data directory within the EDB Postgres Advanced Server 13 installation.

--new-datadir path_to_14_data_directory

Use the --new-datadir option to specify the complete path to the data directory within the EDB Postgres Advanced Server 14 installation.

--username superuser_name

Include the --username option to specify the name of the EDB Postgres Advanced Server superuser. The superuser name should be the same in both versions of EDB Postgres Advanced Server. By default, when EDB Postgres Advanced Server is installed in Oracle mode, the superuser is named enterprisedb. If installed in PostgreSQL mode, the superuser is named postgres.

If the EDB Postgres Advanced Server superuser name is not the same in both clusters, the clusters will not pass the pg_upgrade consistency check.

--old-bindir path_to_13_bin_directory

Use the --old-bindir option to specify the complete path to the bin directory in the EDB Postgres Advanced Server 13 installation.

--new-bindir path_to_14_bin_directory

Use the --new-bindir option to specify the complete path to the bin directory in the EDB Postgres Advanced Server 14 installation.

--old-port 13_port

Include the --old-port option to specify the port on which EDB Postgres Advanced Server 13 listens for connections.

--new-port 14_port

Include the --new-port option to specify the port on which EDB Postgres Advanced Server 14 listens for connections.
