Why there is an empty err log statememt?

Hi,

Recently our customer reported an issue with empty error log statement from
postgres server. I have printed the log snapshot below. The last line is an
empty line. I know this is stupid question but just wanted to understand if
there is any specific reason or it is just a miss.

Jan 29 13:07:29.842238 err CFPU-1 postgres[5696]: [5-*1*] FATAL: could not
send data to WAL stream: server closed the connection unexpectedly

Jan 29 13:07:29.842540 err CFPU-1 postgres[5696]: [5-*2*] This probably
means the server terminated abnormally

Jan 29 13:07:29.842540 err CFPU-1 postgres[5696]: [5-*3*] before or while
processing the request.

Jan 29 13:07:29.842540 err CFPU-1 postgres[5696]: [5-*4*]

We have already shared our analysis that the logs should be read under one
context. In this case red numbered logs should be read in one context.
However the last line is an empty and we are not able to give them proper
justification. So I just wanted to know is the last line left empty
intentionally or is it a miss!
