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.
