Log message:
    Repair misestimation of indexscan CPU costs.  When an indexqual contains
    a run-time key (that is, a nonconstant expression compared to the index
    variable), the key is evaluated just once per scan, but we were charging
    costs as though it were evaluated once per visited index entry.
