postgres_fdw.c around line 4500: /* * If there is a possibility that EvalPlanQual will be executed, we need * to be able to reconstruct the row usingscans of the base relations. * GetExistingLocalJoinPath will find a suitable path for this purpose in * the pathlist of the joinrel, if one exists. We must be careful to * call it before adding any ForeignPath, since the ForeignPathmight * dominate the only suitable local path available. We also do it before --> * reconstruct the row for EvalPlanQual(). Find an alternative local path * calling foreign_join_ok(), since thatfunction updates fpinfo and marks * it as pushable if the join is found to be pushable. */ Should the marked line simply be deleted? If not, what correction is appropriate? regards, tom lane
