Exporting and importing Servers - pgAdmin 4 4.3 documentation
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. The
setup.py
script is used for this purpose.
Note
To export or import servers, 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. For example:
/path/to/python /path/to/setup.py --dump-servers output_file.json
# or, to specify a non-default user name:
/path/to/python /path/to/setup.py --dump-servers output_file.json --user user@example.com
To export only certain servers, use the
--servers
option and list one or
more server IDs. For example:
/path/to/python /path/to/setup.py --dump-servers output_file.json --server 1 2 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. For example:
/path/to/python /path/to/setup.py --load-servers input_file.json
# or, to specify a non-default user name to own the new servers:
/path/to/python /path/to/setup.py --load-servers input_file.json --user user@example.com
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:
