The attached is the patch to tackle the items, against 'replication-orig' branch
in your git repository.

Changes:
* Change PQgetXLogData() to return a malloc'd buffer instead of a
pointer of the internal buffer.
* Remove PQmarkConsumed().
* Introduce a new macro XLogIsNeeded() which encapsulates
(XLogArchivingActive() || XLogStreamingAllowed()).
* Replace read/write_conninfo with just a long-enough field in shared mem.
* Remove 'replication' database, and support a new keyword
'replication' for pg_hba.conf.
* Include system_identifier in the replication startup handshake.
* Add error handling a la bgwriter and have a retry loop within walreceiver.
* Prevent the startup process from getting stuck when launching
walreceiver fails.

Since we might need to change the patch further, I've not modified the
document yet.

Regards,
