From 5788a5670e4a58049b8adc82c4fef97a2c3be327 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 7 May 2017 11:34:31 -0400 Subject: [PATCH] Restore fullname[] contents before falling through in pg_open_tzfile(). Fix oversight in commit af2c5aa88: if the shortcut open() doesn't work, we need to reset fullname[] to be just the name of the toplevel tzdata directory before we fall through into the pre-existing code. This failed to be exposed in my (tgl's) testing because the fall-through path is actually never taken under normal circumstances.
