[postmodern-devel] darcs patch: Correct rational (double-float) formatting

No problem, your detailed patch message made it quite clear what it
was about. I usually do 'darcs send -o filename.patch' and then attach
the resulting file to an e-mail.

I'm not sure Postgres allows expressions in every place where it
allows constants -- but maybe it does. The current approach seems okay
though, since Postgres numerics always use decimal digits, so as long
as the numeric type on the Postgres side has less digits precision
than the writer writes out, we aren't losing any information that
wouldn't be lost anyway.

Best,
