From 25d9bf2e3e66ee2e546c5c523d148ecab6ee1dcc Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 29 Jul 2009 20:56:21 +0000 Subject: Support deferrable uniqueness constraints. The current implementation fires an AFTER ROW trigger for each tuple that looks like it might be non-unique according to the index contents at the time of insertion. This works well as long as there aren't many conflicts, but won't scale to massive unique-key reassignments. Improving that case is a TODO item.
