Thanks for the explanation. Probably we want add/change something to
"54.2. Reporting Errors Within the Server" In this section I see:

Therefore, elog should be used only for internal errors and low-level debug logging.

to use elog for internal errors and low-level debug logging over
ereport, then above might be better changed something like:

Therefore, elog should be used only for internal errors and low-level
