Very well, if I was harsh I apologise, but maybe you should look at the 
embedding guide here <http://code.google.com/apis/v8/embed.html> and 
decide how well it is likely to work for PostgreSQL in pure C. The 
advice was not just "spidermonkey might be better". It was that a C++ 
oriented API like this (throwing exceptions among other things) was not 
likely to work, or at least to work as well as a pure C API.

And, frankly, pure PL speed in a language like JS, that is likely to be 
used mainly as glue, is not likely to be a concern for most uses.

If someone is going to work on a JS engine for PostgreSQL (which I think 
is a good idea, actually) I want them to work on one that is likely to 
succeed.
