From a0381f267912063547d7911f2c4600da20ded024 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 29 Jul 2009 15:57:39 +0000 Subject: [PATCH] Fix a thinko introduced into CountActiveBackends by a recent patch: we should ignore NULL array entries, not non-NULL ones. This had the effect of disabling commit_delay, and could have caused a crash in the rare race condition the patch was intended to fix.
