try/catch/return crashes postgres server about plv8 HOT 3 CLOSED

btw, if someone happens to run into this and is looking for a quick fix to move 
on, it seems that errors from js-land have properties, while errors bubbled up 
from postgres to js-land do not.  So as long as that hold true, in the catch 
block I do this before calling return:

if (Object.keys(e).length === 0) throw e;

It is working in all my tests, and prevents a bad query from causing pg to die

Hmm, it doesn't reproduce for me.  I'm using the latest git master, but I don't 
think it matters.  Which v8 version are you using?  Also let me know about OS.

Closing as WontFix as the reproduction is not clear.  Please change the status 
again if you think otherwise.
