Thanks for the data! I've been able to reproduce the issue (load into
12, pg_upgrade to 14 and run the query). After bisecting this for a
while, this seems like a bug in PG13 commit
commit 911e70207703799605f5a0e8aad9f06cff067c63 (HEAD)
Author: Alexander Korotkov <akorotkov@postgresql.org>

Implement operator class parameters
...
It works fine when upgrading to an earlier build, and crashes since this
commit. I haven't investigated this further, but I guess there's some
thinko in gist_ltree_ops, affecting how we interpret existing indexes.
Alexander, any ideas?
regards
