@vladiksun I was able to get an index working for WHERE -
```
psql-15.3-5432-pgsql=# select
any_profile
from ag_catalog.cypher('test_graph',$$
EXPLAIN ANALYZE MATCH (any_profile:`profile` { hidden: false })
WHERE any_profile.pet = 'dog'
RETURN any_profile
$$
) as (any_profile ag_catalog.agtype);

I still need to do other tests to verify that the changes don't cause any
side effects. There are 2 issues here -
- Are the functions truly IMMUTABLE? This needs to be verified.
- The `profile_pet_btree_idx3 `was not correct. But, without being able to
create it, you wouldn't know.
