Can you verify tblpuorderstatus and tblpuorderstatushistory have all
indexes accounted for on both servers?  It seems incredible server
would prefer wading through 11M records to 1298 nestloop.  I'm curious
what plans you get if you try playing around with:

set enable_seqscan=false;
set enable_hashjoin=false;

...but I think we have two possibilities here:
1. schema mismatch
2. planner bug

I never got an answer to my question.

Have you verified that postgresql.conf is the same of both 9.5 & 9.6?
