Is it possible (or will it be possible) to issue CREATE TEMP TABLE statements on the read-only slave nodes in master-slave streaming replication in recent version of PostgreSQL (9.4+)?

Currently it is not possible. There are two plans related to this issue: 1. global temp tables, 2. logical replication. The work on logical replication is near finalization and probably it will be available in 9.6.
