Re: seg fault crashed the postmaster

The number of matching rows on these queries is anything from 0 to 10000.  I don't think I can tell how many would have matched on the ones that crashed.  Although I suspect it would have been toward the 10000 end.   I've been trying to get a reproducable test case with no luck so far.

I assume you can now see the plan?  I uploaded it twice, once via gmail and once on Nabble.

Here are all the non-default settings:
