Out of respect to existing log-processing programs, I tried to adhere to
the pgsql traditional (pre-7.1) format, except that I'd added a 4-digit
year I'd been patching since 6.5.2, which probably ended up breaking them
anyway.

Yes, microsecond was a typo. I meant milliseconds.

That'd be an improvement. Unfortunately, the ISO 8601 standard is not
much more readable:

2001-05-13T10:19:44,085-05:00

That's a literal 'T' designating the time portion and a comma separating
seconds and milliseconds (http://www.iso.ch/markete/8601.pdf).
