There are multiple configuration files that are read at startup by pgAdmin. These files can be used to modify the default configuration options or to add any configuration which a user needs to define only once. The configuration files are as follows:
This is the main configuration file, and should not be modified. It can be used as a reference for configuration settings that may be overridden in one of the files which we will discuss further.
This file is read after the config.py and is intended for packagers to change any settings that are required for their pgAdmin distribution. This may include certain paths and file locations specific to the packaging or platform. This file is optional and must be created in the same directory as config.py.
This file is read after config_distro.py and is intended for end users to change any default or packaging specific settings. This may include settings like adding oAuth or LDAP config, changing the application mode or any other configuration which the end user might want to change. This file is also optional and can be created in the same directory as config.py.
This file is read after config_local.py and is intended for system administrators to include settings that are configured system-wide from a secure location that unprivileged users can not modify, outside the pgAdmin installation. The location for this file varies based on platform, and is optional. The location of file based on platform is as follows:
You can check all the configurations available in config.py from here.
Config files can be used to modify the pgAdmin configurations by users, packager manager or system administrators to handle how applications loads and behaves.
