> Background:
> In previous single node DB, user always deploy testing code on another 
> testing DB. Now the data maintained in HAWQ grows enormously, so it is hard 
> to deploy a testing hawq with the same test data. 
> So user need to run some testing UDF or deploy some UDFs which lack of 
> testing the whole data directly onto hawq in production env, which may crash 
> in PL/R or R code. Sometimes poorly written query leads to postmaster reset 
> causing all running jobs to be cancelled and rolled back. Customer often sees 
> this as a HAWQ issue even if it is a user code issue. So we need to separated 
> from postgres process, and change inter process communication from shared 
> memory to others(e.g. pipe, socket and so on).
