pg_user problem

Hi, please apply following patches to rewrite/rewriteManip.c.
This seems to fix the "pg_user problem." (I am not very familiar
with the rule/rewrite area, so my understanding may be wrong)
The original code sets varlevelsup even if the node is not
variable node. This assumption is not always correct, for example
with the password column of pg_user view.
Anyway, with the patch the select_view test is now ok on my LiuxPPC
box.
