Tom Lane a7b965382c Better fix for permissions tests in excluded subqueries. ... This reverts the code changes in 50c137487c, which turned out to induce crashes and not completely fix the problem anyway. That commit only considered single subqueries that were excluded by constraint-exclusion logic, but actually the problem also exists for subqueries that are appendrel members (ie part of a UNION ALL list). In such cases we can't add a dummy subpath to the appendrel's AppendPath list without defeating the logic that recognizes when an appendrel is completely excluded. Instead, fix the problem by having setrefs.c scan the rangetable an extra time looking for subqueries that didn't get into the plan tree. (This approach depends on the 9.2 change that made set_subquery_pathlist generate dummy paths for excluded single subqueries, so that the exclusion behavior is the same for single subqueries and appendrel members.) Note: it turns out that the appendrel form of the missed-permissions-checks bug exists as far back as 8.4. However, since the practical effect of that bug seems pretty minimal, consensus is to not attempt to fix it in the back branches, at least not yet. Possibly we could back-port this patch once it's gotten a reasonable amount of testing in HEAD. For the moment I'm just going to revert the previous patch in 9.2.		13 years ago
