commit    d12afe114403aee962ddca900842e4460bd17f68
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Sun Mar 29 19:04:09 2015 +0000
First released in: 9.5.0, 9.0.20, 9.1.16, 9.2.11, 9.3.7, 9.4.2

    Add vacuum_delay_point call in compute_index_stats's per-sample-row loop.
    
    Slow functions in index expressions might cause this loop to take long
    enough to make it worth being cancellable.  Probably it would be enough
    to call CHECK_FOR_INTERRUPTS here, but for consistency with other
    per-sample-row loops in this file, let's use vacuum_delay_point.
    
    Report and patch by Jeff Janes.  Back-patch to all supported branches.
