This patch, which seems to be the latest version, no longer applies,
and has not been updated based on the previous provided review
comments.

Also, this diff hunk looks scary to me:

+       if (must_use_query)
+               ereport(ERROR,
+                               (errcode(ERRCODE_INSUFFICIENT_PRIVILEGE),
+                                errmsg("cannot SELECT from primary
key of relation \"%s\"",
+                                               RelationGetRelationName(rel))));
+

What's the justification for that?
