Read over the patch and it looks good.

One minor "the" omission (in a couple of places, copy-paste style):

+ See <xref linkend="wal-configuration"/> for more information about
+ internal WAL function <function>XLogWrite</function>.

"about *the* internal WAL function"

Also, I'm not sure why you find omitting documentation that the millisecond
field has a fractional part out to microseconds to be helpful.
