pgsql: Optimize get_jsonb_path_all avoiding an iterator - Mailing list pgsql-committers

Optimize get_jsonb_path_all avoiding an iterator

Instead of creating an iterator object at each step down the JSONB
object/array, we can just just examine its object/array flags, which is
faster.  Also, use the recently introduced JsonbValueAsText instead of
open-coding the same thing, for code simplicity.
