Query planner matches compound indexes incrementally. Bug exists in this part of the code such that, if the predicate is on
A and Band if it matches first with indexA_C, then later stages of the incremental check instead of looking for index matchA_B, it looks forA_C_B. This patch fixes that issue.This fixes #46 and also fixes #38
