      pg_current_wal_location     -> pg_current_wal_lsn

• Fix query cache hang when used by node.js. (Tatsuo Ishii)

  See [pgpool-general: 5511] for more details.

• Deal with PostgreSQL 10 in streaming replication delay checking. (Tatsuo Ishii)

• Fix query cache memory leak. (Tatsuo Ishii)

  Clearing cache buffers in case of no oid queries (like BEGIN , CHECKPOINT , VACUUM , etc) should have been done, but it did not.

• Fix corner case bug in Pgpool-II starting up. (Tatsuo Ishii)

  It is possible that a failover request is accepted before primary node is searched. This leads Pgpool-II to a strange state: there's no primary node if the failed node was a primary node (even if new primary node exists as a result of promotion of existing standby).

  See [pgpool-hackers: 2321] for more details.
