c3bc5585d9 Add sanity check for extension version
This should cover the cases where the "repmgr" extension was installed
manually but not updated, or an upgrade was not fully completed.

a459c60145 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.

Also noted in GitHub #510.

dc8ffd30c6 "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.

62ac56c3f5 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.

c79852cce0 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.

3907a545b0 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.

b2348c9a70 repmgrd: improve promotion script failure handling
While scanning for a new primary following a promotion script failure,
repmgrd was treating a witness server as a potential new primary
and would attempt to "follow" it. Fortunately "repmgr standby follow"
would do the right thing and choose the actual primary, if available,
otherwise do nothing, so the cluster would eventually end up in the
correct state, albeit for the wrong reason.

By skipping the witness server as a potential new primary,
repmgrd will do the right thing if the original primary does come
back online, i.e. resume monitoring as before.

ad03885b72 repmgrd: fix parsing of -d/--daemonize option
The getopt API doesn't cope well with optional arguments to short form options,
e.g. "-o foo", so we need to check the next argument value to see whether it looks
like an option or an actual argument value.
