Clean up optimizer's handling of indexscan quals that need to be
commuted (ie, the index var appears on the right). These are now handledthe same way as merge and hash join quals that need to be commuted: theactual reversing of the clause only happens if we actually choose the pathand generate a plan from it. Furthermore, the clause is only reversed inthe 'indexqual' field of the plan, not in the 'indxqualorig' field. Thisallows the clause to still be recognized and removed from qpquals of upperlevel join plans. Also, simplify and generalize match_clause_to_indexkey;now it recognizes binary-compatible indexes for join as well as restrictionclauses.1 parentaae034d commit8f9f6e5
