This wouldn't handle functional indices in OR...
So, I added indexqualorig list to the IndexScan node:
indexqual = fix_indxqual_references (indexqualorig)
- indxqualorig' Var-s references heap tuple...
Regression tests are ok.
Patch made for CURRENT tree - let me know if there will

It's better to gmake clean in backend dir...
Patch also fixes EXPLAIN for indices in OR: all indices
used are explained now.
