From 13fe298ca06f5390df5edf073cf401f9f0b67458 Mon Sep 17 00:00:00 2001 From: Simon Riggs Date: Fri, 22 Mar 2013 12:01:16 +0000 Subject: [PATCH] Change commit_delay to be SUSET for 9.3+ Prior to 9.3 the commit_delay affected only the current user, whereas now only the group leader waits while holding the WALWriteLock. Deliberate or accidental settings to a poor value could seriously degrade performance for all users. Privileges may be delegated by SECURITY DEFINER functions for anyone that needs per-user settings in real situations.
