Import/Export Servers — pgAdmin 4 9.15 documentation

# Import/Export Servers

Server definitions (and their groups) can be exported to a JSON file and re-imported to the same or a different system to enable easy pre-configuration of pgAdmin.

## Using pgAdmin 4 GUI

To launch the Import/Export Servers… tool, navigate through Tools on the menu bar to click on the Import/Export Servers option.

- Use the Import/Export field to select the Server Groups/Servers to be imported or exported.

- Use the Filename field to select the JSON file to import servers or create the new file in case of Export where the servers to be exported in the JSON format.

- Use the Remove all the existing servers? field to specify whether to remove all the existing servers or not before importing the new selected servers. This field is applicable only in case of Import Servers.

Click the Next button to continue, or the X button to close the wizard.

- Select the Server Groups/ Servers to be imported/exported.

Click the Next button to continue, or the X button to close the wizard.

Check the summary of the servers that are going to be imported/exported on the Summary page.

Click the Finish button to close the wizard.

## Using ‘setup.py’ command line script

Note

To export or import servers using `setup.py` script, you must use the Python interpreter that is normally used to run pgAdmin to ensure that the required Python packages are available. In most packages, this can be found in the Python Virtual Environment that can be found in the installation directory. When using platform-native packages, the system installation of Python may be the one used by pgAdmin.

### Exporting Servers

To export the servers defined in an installation, simply invoke `setup.py` with the `dump-servers` command line option, followed by the name (and if required, path) to the desired output file. By default, servers owned by the desktop mode user will be dumped (pgadmin4@pgadmin.org by default - see the DESKTOP_USER setting in `config.py`). This can be overridden with the `--user` command line option. There can be multiple configurations of pgAdmin on the same system. To dump the servers from specific pgAdmin config DB file, `--sqlite-path` option can be used. It is also recommended to use this option when running pgAdmin in desktop mode. By default SQLITE_PATH setting in `config.py` is taken. For example:

    /path/to/python /path/to/setup.py dump-servers output_file.json

    # or, to specify a non-default user name and auth source (the default is Internal):

    /path/to/python /path/to/setup.py dump-servers output_file.json --user user@example.com --auth_source ldap

    # to specify a pgAdmin config DB file:

    /path/to/python /path/to/setup.py dump-servers output_file.json --sqlite-path /path/to/pgadmin4.db

To export only certain servers, use the `--server` option and list one or more server IDs. For example:

    /path/to/python /path/to/setup.py dump-servers output_file.json --server 1 --server 2 --server 5

### Importing Servers

To import the servers defined in a JSON file, simply invoke `setup.py` with the `load-servers` command line option, followed by the name (and if required, path) of the JSON file containing the server definitions. Servers will be owned by the desktop mode user (pgadmin4@pgadmin.org by default - see the DESKTOP_USER setting in `config.py`). This can be overridden with the `--user` command line option. There can be multiple configurations of pgAdmin on the same system. The default behaviour is for the imported servers to be added to the existent list, which might lead to duplicates. This can be overridden with the `--replace` command line option, which will replace the list of servers with the newly imported one. To load the servers into a specific pgAdmin config DB file, `--sqlite-path` option can be used. It is also recommended to use this option when running pgAdmin in desktop mode. By default SQLITE_PATH setting in `config.py` is taken. For example:

    /path/to/python /path/to/setup.py load-servers input_file.json

    # or, to replace the list of servers with the newly imported one:

    /path/to/python /path/to/setup.py load-servers input_file.json --replace

    # or, to specify a non-default user name and auth source (the default is Internal) to own the new servers:

    /path/to/python /path/to/setup.py load-servers input_file.json --user user@example.com

    # to specify a pgAdmin config DB file:

    /path/to/python /path/to/setup.py load-servers input_file.json --sqlite-path /path/to/pgadmin4.db

If any Servers are defined with a Server Group that is not already present in the configuration database, the required Group will be created.

### JSON format

The JSON file format used when importing or exporting servers is quite straightforward and simply contains a list of servers, with a number of attributes. The following attributes are required to be present in every server definition: Name, Group, Port, Username, SSLMode, MaintenanceDB and one of Host, HostAddr or Service.

Password fields cannot be imported or exported.

The following example shows both a minimally defined and a fully defined server:

    {
        "Servers": {
            "1": {
                "Name": "Minimally Defined Server",
                "Group": "Server Group 1",
                "Port": 5432,

                "KerberosAuthentication": true,

                    "connect_timeout": 10,
                    "passfile": "/Users/<user>/.pgpass",
                    "sslcert": "/Users/<user>/.ssh/cert"
                },
                "Tags": [
                    {
                        "color": "#EC0BB4",
                        "text": "Development"
                    }
                ],
                "PostConnectionSQL": "set timezone='America/New_York'"
            }
        }
    }

Note

If you’re running pgAdmin in Server Mode, the values for parameters that require file paths should be specified relative to the user’s home directory which is /<DATA_DIR>/storage/<user_id>/. If DATA_DIR is not specified, then it will be /var/lib/pgadmin/storage/<user_id>/
