5886772cdb Teach witness repmgrd to deal with the absence of a primary 
Previously it would refuse to start if the primary was not reachable,
the thinking being that it's pointless trying to monitor an incomplete
cluster.

However following an aborted failover situation, repmgrd will restart
monitoring and on the witness server, this will lead to it aborting
itself due to to continuing absence of primary.

To resolve this, witness repmgrd will now start monitoring in degraded
mode if no primary is found in the hope a primary will reappear at
some point.

71dda21b85 "witness register": don't try and read nodes table if it doesn't exist 
Previously, "repmgr witness register --dry-run" would attempt to check
for records in the nodes table, but that might not exist yet. Skip
that check if the repmgr extension is not yet installed.

Implements GitHub #513.

a554914854 Avoid defining variable-length arrays 
As of PostgreSQL commit d9dd406f, variable length arrays are no longer
permitted. As they're not actually required anyway, just define appropriate
constants.

79e79bd5f2 "standby switchover": close all connections used to check repmgrd status 
The connections used to check repmgrd status on all nodes were not being
closed if repmgrd was not running. Normally this wouldn't be a huge
problem as they will go away when repmgr terminates or the PostgreSQL
server restarted. However, if shutdown mode is "smart", the open
connection on the demotion candidate will cause the shutdown operation
to fail until repmgr times out.

0842560a88 repmgrd: handle case where upstream is no longer primary 
If the upstream comes back on line (e.g. after a switchover), and its
status is no longer primary, restart monitoring to ensure the correct
primary (potentially the current node) is being monitored.

8bec4946bc Ensure witness repmgrd detects change in upstream's role 
This ensures that e.g. after a switchover, repmgrd running on a witness
node will automatically detect the new primary and monitor that.

3ab22f9442 repmgrd: ensure witness node doesn't try and follow another witness 
Theoretically there should never be more than one witness node
visible here, but it's not impossible to rule it out, so add a
check just in case.
