Ensure tableoid reads correctly in EvalPlanQual-manufactured tuples.
The ROW_MARK_COPY path in EvalPlanQualFetchRowMarks() was just settingtableoid to InvalidOid, I think on the assumption that the referencedRTE must be a subquery or other case without a meaningful OID. However,foreign tables also use this code path, and they do have meaningfultable OIDs; so failure to set the tuple field can lead to user-visiblemisbehavior. Fix that by fetching the appropriate OID from the rangetable.There's still an issue about whether CTID can ever have a meaningfulvalue in this case; at least with postgres_fdw foreign tables, it does.But that is a different problem that seems to require a significantlydifferent patch --- it's debatable whether postgres_fdw really wants touse this code path at all.Simplified version of a patch by Etsuro Fujita, who also noted theproblem to begin with. The issue can be demonstrated in all versionshaving FDWs, so back-patch to 9.1.1 parent26d2c5d commit443fd05
