Please find attached the complete patch for alter rename rule. I have
followed all the suggestions. Followings things are added in this updated
1) Disallow alter rename of ON SELECT rules.
2) Remove warning.
3) Varibles are lined up.
4) Used qualified_name instead of makeRangeVarFromAnyName.
5) Throw appropriate error if user tries to alter rename rule on irrelavent
object(e.g index).
6) Psql tab support added
7) Regression test cases added.
8) Documentation added.
