No data at all needed in table.
In fact just create database + create 3 those objects is enough to reproduce it.

Also i did a test-built of HEAD (commit: b54f7a9ac9646845138f6851fdf3097e22daa383)

An get to same failure also.

./configure --prefix=/home/huehner/oss/postgresql/git/install
make -j8 install
bin/initdb -D pg_data
bin/postmaster -D pg_data -p 5555

So question is what in my env is triggering it?

Running intel 64bit debian/unstable here.
