Was the assertion failure on Postgres Pro's fork? I understand that
there are differences in this exact area on the forked version,
because it has to deal with two representations -- the fork had
INCLUDE indexes before the community version, which explicitly
represents the number of attributes in pivot tuples.

I wouldn't usually ask this, but the failure is very basic. It's hard
to believe that it would take this long to notice it.

I also note that you have "fsync = off". I suppose that that might be
relevant, too.
