From 598ac10be1c20961baac44db773eb826f788fdfa Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Wed, 18 May 2022 18:33:04 +0200 Subject: Make EXPLAIN MERGE output format more compact We can use a single line to print all tuple counts that MERGE processed, for conciseness, and elide those that are zeroes. Non-text formats report all numbers, as is typical.
