The best thing about postico is that it has made my life easier by providing me with a simple tool for managing all of my databases I am using at one time in linux environment.
It also makes sure that everything works flawlessly from being able to be used within different environments like docker containers as well as natively running under Linux itself which can sometimes cause issues when you are not aware this exists. Sometimes there will pop up errors where some things don't work but they usually go away after restarting or refreshing browser window so no big deal! Make your own rules/workflows depending on what needs done. One database could have multiple users who need access to their data depending upon how many people would want to utilize them while others may only require 1 person utilizing them instead of having 5-6 separate ones just for themselves.
