The commit by the second patch added several GUC descriptions:

Some of them, commit_timestamp_buffers, transaction_buffers,
subtransaction_buffers use 0 to mean auto-tuning based on
shared-buffer size. I think it's worth adding an extra_desc such as "0
to automatically determine this value based on the shared buffer
size".
