The following documentation comment has been logged on the website:

Description:

The setting log_temp_files will enable logging of the usage of temporary
files, including their size in the log files. The setting is given in
kilobytes, which is clearly documented. However, I could not find any clear
documentation that describes the unit of size that is used in the logfiles
themselves, the log line is something like "profiles(at)profiles LOG:
temporary file: path "base/pgsql_tmp/pgsql_tmp31863.1", size 3137536" but
there is no size unit in the logfile or in the settings documentation. Can
you add whether the log line is in bytes/kilobytes/megabytes?
