commit    722f31f786164d5bffd801be6fe31515cc3f2ece
Author:   Bruce Momjian <bruce@momjian.us>
Date:     Fri Jul 29 03:17:55 2005 +0000
First released in: 8.1.0

    Thank you for applying patch --- regexp_replace.
    
    An attached patch is a small additional improvement.
    
    This patch use appendStringInfoText instead of appendStringInfoString.
    There is an overhead of PG_TEXT_GET_STR when appendStringInfoString is
    executed by text type. This can be reduced by appendStringInfoText.
