From b17870d754665c4b431d3ce4de6676832a0b10a0 Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Fri, 3 Nov 2017 20:36:32 +0100 Subject: [PATCH] Fix thinkos in BRIN summarization The previous commit contained a thinko that made a single-range summarization request process from there to end of table. Fix by setting the correct end range point.
