Supported PostgreSQL Versions

Data Management for VMware Tanzu supports provisioning database Service Instances running these PostgreSQL versions:

  • 10.15.0 and 10.17.0
  • 11.10.0 and 11.12.0
  • 12.7.0


When you create a PostgreSQL database Service Instance with Data Management for VMware Tanzu, you configure certain PostgreSQL properties.

Database Instance Configuration

The Database Instance Configuration properties identify the name of the default database, the database server port number, and the database administrator user credentials.

Property Name Description Default Value
Database Name The name of the default database. PostgresDB
Database Port No The port number on which the database server runs. (Read-only) 5432
Admin Username The database administrator user name. admin
Admin Password The password for the database adminstrator. Admin!23Admin
Note: Data Management for VMware Tanzu does not support changing the Admin Password from the console or API. You must change this password using a database client. If you change the password in this manner, the new password is not reflected in DMS.

DB Options Configuration

The DB Options Configuration properties control certain runtime characteristics of the PostgreSQL database. These are:

Property Name Description Default Value Restart Required on Update?
TimeZone The time zone for the PostgreSQL server.1 GMT Yes
max_connections The maximum number of concurrent connections allowed to the PostgreSQL server. Choose a suitable value based on CPU, memory, and application requirements. 100 Yes
log_connections Enable or disable logging of connection attempts and successful completion of authentication. off No
locale The language, sorting, number formatting, date/time, currency, etc. preference for the PostgreSQL server.2
Note: You can set the locale only at database creation time; you cannot set this parameter after you create the database.

The following PostgreSQL locales are available in this release of DMS:
Note: If you want to set a parameter to the PostgreSQL server default, you must remove/clear the entry.

1 Run the following PostgreSQL query to obtain the possible time zone values: SELECT name FROM pg_timezone_names;

2 Be sure to consult the PostgreSQL documentation before you set the locale or related lc_xxx options.

Connecting to a PostgreSQL Database Service Instance

To access a PostgreSQL database Service Instance, the host on which the client application is running must have connectivity to the Application Network configured for the instance.

You can use any SQL client application to connect to a database in your PostgreSQL Service Instance. To connect, you must be able to identify the FQDN of the PostgreSQL server host, the port on which the server is running, and the database name. You must also have the PostgreSQL admin credentials on hand. You can obtain this information from the Data Management for VMware Tanzu console as described in Locating the Database Service Instance Connection Parameters.

Using TLS with a PostgreSQL Database Service Instance

Refer to SSL Support in the PostgreSQL documentation for more information on using SSL/TLS with PostgreSQL.

Note: Data Management for VMware Tanzu does not support verify-full TLS configuration for client applications connecting to a Service Instance.

Requiring TLS

Note: The default SSL/TLS configuration for PostgreSQL on Data Management for VMware Tanzu does not require secure client connections.

You can configure a PostgreSQL Service Instance to require SSL/TLS client connections during creation or after provisioning as follows:
