If the problem went away after a restart, the bogus value could not have been on disk but must have been in a bad in-memory copy of an index page. Which suggests a hardware glitch ... although if you are using contrib/ltree, I recall seeing several bug fixes go by recently that were described as fixing potential ltree-index corruption issues. regards, tom lane
