From 90d76525c5cc2f3f4781351a1d99be839dfa2874 Mon Sep 17 00:00:00 2001
From: Neil Conway <neilc@samurai.com>

Subject: Add resetStringInfo(), which clears the content of a StringInfo, and
 fixup various places in the tree that were clearing a StringInfo by hand.
 Making this function a part of the API simplifies client code slightly, and
 avoids needlessly peeking inside the StringInfo interface.
