Re: plpython does not honour max-rows

Thanks for the quick response. Chapter 46.6.1 says that max-rows is an
optional row limit. Unless I missed it there is nothing in the
documentation about zero meaning all rows. Wouldn't it rather be like SQL
LIMIT 0 meaning all rows?
Anyway it was surprising gotcha, but of course easy to code around.
