who can fix RENAME in plpgsql

Hi,

i know that the documentation said low priority on this but i absolutely
need to rewrite new because i must use it in a query within an plpgsql
function. Actually i try to use an older plpgsql version with postgres
7.3.2 by copying the plpgsql sources from 7.2.4 to the sourcetree of
7.3.2 i hope this will work and that i can use rewrite then, but i would
appreciate if there is anybody out there who can fix the bug.

Best regards
Georg Steffers
