This is most likely caused by trying to follow a bogus item pointer in
an index. 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.
