Very long, I'm afraid.  I only observed it once, and according to the
logging database, about 4e9 random queries were generated since testing
with 9.5 code.

I could probably speed it up by creating lots of additional BRIN indexes
in the regression database, and by compiling a sqlsmith that generates
update statements only.
