pgAdmin

https://www.pgadmin.org/download/pgadmin-4-python/

A Python package is available for those wishing to run pgAdmin as a web application in a Python environment. Note that the packages do not include the Desktop Runtime.

pgAdmin is available on PyPi. To install it, create a virtual environment as required, and then use pip to install. Note that pgAdmin will run in server mode, using system-wide paths so you may need to create them first:

$ sudo mkdir /var/lib/pgadmin
$ sudo mkdir /var/log/pgadmin
$ sudo chown $USER /var/lib/pgadmin
$ sudo chown $USER /var/log/pgadmin
$ python3 -m venv pgadmin4
$ source pgadmin4/bin/activate
(pgadmin4) $ pip install pgadmin4
...
(pgadmin4) $ pgadmin4
NOTE: Configuring authentication for SERVER mode.

Enter the email address and password to use for the initial pgAdmin user account:
