Answer 1

PostgreSQL doesn't support parallel processing of one query - so there there are no feature like parallel pipeline functions.

Answer 2

PostgreSQL 9.6+ now (to some extent) parallelizes a single query (without much effort from the user). However, since the new feature is still being ironed, how much this benefits your given query, may vary.
