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.
