From 23b8a0ce61c0fac72c9b40acb875bb0ab0a5b915 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Wed, 29 Jan 2003 01:08:42 +0000
Subject: Repair array subscript overrun identified by Yichen Xie.  Reduce the
 value of MAX_TIME_PRECISION in floating-point-timestamp-storage case from 13
 to 10, which is as much as time_out is actually willing to print. (The
 alternative of increasing the number of digits we are willing to print looks
 risky; we might find ourselves printing roundoff garbage.)
