Be sure to pull up the subquery's hasRowSecurity flag when flattening a subquery in pull_up_simple_subquery(). This isn't a bug today because we don't look at the hasRowSecurity flag during planning, but it could easily be a bug tomorrow. Likewise, make rewriteRuleAction() pull up the hasRowSecurity flag when absorbing RTEs from a rule action. This isn't a bug either, for the opposite reason: the flag should never be set yet. But again, it seems like good future proofing. Add a comment explaining why rewriteTargetView() should *not* set hasRowSecurity when adding stuff to securityQuals. Improve some nearby comments about securityQuals processing, and document that field more completely in parsenodes.h. Patch by me, analysis by Dean Rasheed.
