data_directory_mode
A read-only preset configuration parameter reporting the permissions of the data directory
data_directory_mode is a preset configuration parameter reporting the permissions of the data directory defined by the data_directory parameter at startup.
data_directory_mode was added in PostgreSQL 11.
Default value
The default value for data_directory_mode is: 0700.
Note that as a preset configuration parameter, data_directory_mode does not have a default value per-se. It can however be implicitly set when initialising a data directory with initdb using the -g/--allow-group-access, or by manually setting the data directory permissions to one of either 0700 (drwx------) or 0750 (drwxr-x---) before (re)starting PostgreSQL. Other combinations of permission settings are not permitted.
