From 389af951552ff2209eae3e62fa147fef12329d4f Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 25 Feb 2011 18:56:23 -0500 Subject: Support data-modifying commands (INSERT/UPDATE/DELETE) in WITH. This patch implements data-modifying WITH queries according to the semantics that the updates all happen with the same command counter value, and in an unspecified order. Therefore one WITH clause can't see the effects of another, nor can the outer query see the effects other than through the RETURNING values. And attempts to do conflicting updates will have unpredictable results. We'll need to document all that. This commit just fixes the code; documentation updates are waiting on author.
