Postgresql Streaming Replication
Support for standard WAL based streaming replication for
postgresql guests. Sets up read-only hot standby servers.
Basic replication is supported for 9.3, but promote
requires pg_rewind which is only supported for 9.4 and
greater. Promote currently only works with single
master-replica configurations (see TODO and associated
bug 1553339 for details)
Test changes:
- moved the replication promote tests to a separate group
- skipped known issues with bug reference
Change-Id: I519fa58d786edddb09bf14ce7629e1be51b62600
Implements: bp/pgsql-replication
