RE: drop a histogram on a single column

I believe this will work:
Just find out what the current num_distinct is, then run the above procedure to manually set it to the same value and I believe this will have the side-effect of removing the histogram from that column while keeping all other stats intact.
I'm not sure if this is a documented side-effect so you might want to test first and use at your own risk.

Anyone know a way to drop a histogram on single column?
