Log message:
    Fix some planner performance problems with large WHERE clauses, by
    introducing new 'FastList' list-construction subroutines to use in
    hot spots.  This avoids the O(N^2) behavior of repeated lappend's
    by keeping a tail pointer, while not changing behavior by reversing
    list order as the lcons() method would do.
