The relationship between 'min_wal_size', 'max_wal_size' and 'wal_segment_size' is not record.

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/13/bug-reporting.html
Description:

configuration option 'min_wal_size' and 'max_wal_size' must be at least
twice 'wal_segment_size', but none of these information was mentioned in the
description of these three configuration options, nor in related document in
https://www.postgresql.org/docs/11/runtime-config-wal.html,
https://www.postgresql.org/docs/11/runtime-config-preset.html, and
https://www.postgresql.org/docs/11/wal-configuration.html.

Although the default value of 'min_wal_size' and 'max_wal_size' is much
larger than 'wal_segment_size', in case of some corner case, I think it is
better to supplement this information in the doc.
