Shouldn't be below statement:

"Although the jsonb_path_ops operator class supports only queries with the
@> operator, it has notable performance advantages over the default operator
class jsonb_ops."

corrected to:

"Although the jsonb_path_ops operator class supports only queries with the ?
operator, it has notable performance advantages over the default operator
class jsonb_ops."

Uh, no, I don't think so:

regression=# select oid from pg_opfamily where opfname = 'jsonb_path_ops';
oid
------
4037
(1 row)

regression=# select amopopr::regoperator from pg_amop where amopfamily = 4037;
amopopr
-----------------
@>(jsonb,jsonb)
(1 row)

Hi Tom,

Then I guess I will need to read that part of the chapter again.
Many thanks for the clarification.

Gokhan.
