# TEST repmgr100
# TEST Basic test of repmgr's multi-process master support.
# TEST
# TEST Set up a simple 2-site group, create data and replicate it.
# TEST Add a second process at the master and have it write some
# TEST updates.  It does not explicitly start repmgr (nor do any
# TEST replication configuration, for that matter).  Its first
# TEST update triggers initiation of connections, and so it doesn't
# TEST get to the client without a log request.  But later updates
# TEST should go directly.
