log_filename()

We got the comment on the docs:

log_filename(string) is misleading, since it really doesn't use a
strftime pattern, but instead a reimplementation of strftime, in order
to be cross-platform. There is no documentation on this except to look
in src/timezone/strftime.c (the function is called pg_strftime)

Is it true?
