The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/bug-reporting.html Description:
Using a mount point directly as the data_directory is not recommended, but this tip is not recorded in the doc https://www.postgresql.org/docs/11/runtime-config-file-locations.html or any where else. I suggest adding this tip in the doc when introducing configuration option 'data_directory' in https://www.postgresql.org/docs/11/runtime-config-file-locations.html.
