Update pgadmin

pgadmin4 on web by python

$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

Change port, by default is 5050 but if you want to change(on the venv):

$PGADMIN_INT_PORT=6060 pgadmin4/bin/pgadmin4
 

Change the credentials(on the venv):

$pgadmin4/bin/pgadmin4-cli add-user email@gmail.com password


 

Remove credentials:

$ls /var/lib/pgadmin/storage
 

Enable remote access to pgadmin4

$vi pgadmin4/lib/python3.10/site-packages/pgadmin4/config.py
