From cdf5a004bb7cc78e70ffe5213049dc853b93e699 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Sat, 6 May 2017 22:21:37 -0400 Subject: Allow queries submitted by postgres_fdw to be canceled. Back-patch of commits f039eaac7131ef2a4cf63a10cf98486f8bcd09d2 and 1b812afb0eafe125b820cc3b95e7ca03821aa675, which arranged (in 9.6+) to make remote queries interruptible. It was known at the time that the same problem existed in the back-branches, but I did not back-patch for lack of a user complaint. Michael Paquier and Etsuro Fujita, adjusted for older branches by me. Per gripe from Suraj Kharage. This doesn't directly addresss Suraj's gripe, but since the patch that will do so builds up on top of this work, it seems best to back-patch this part first.
