The cited error message appears when loading the attached file (a cut-down
version of a local development version of the information schema) and then
running
select * from problem_schema.element_types;
On the last seven lines of the file I've marked a part that, when removed,
makes the problem disappear, which might give a hint. Besides that, I'm
clueless.
My local tree was last updated June 28.
