b292ac61f8 "standby switchover": update hint 2018-03-30 09:12:21 +09:00

3e1f0ec168 repmgr: move demoted primary check to the final step during switchover 
This will give the demoted primary more time to start up as a standby,
during which "standby follow" can be executed on sibling nodes, if
specified.

6f9a1f975e repmgr: poll demoted primary after restart during switchover 
During a switchover operation, once the demoted primary has been restarted
as a standby, repmgr attempts to reconnect to verify its status and drop
any redundant replication slots. However it's possible the standby may still
be in the startup phase, so poll for "standby_reconnect_timeout" seconds
before giving up.

Addresses GitHub #408.

96cf06204c doc: add note about remote command execution 
When executing a command on a remote server, repmgr expects the remote binary
to be in the same location as the local binary. It's reasonable to assume
repmgr will be deployed in a unified environment; if not, the onus is on the
user to ensure repmgr can find the remote binary, e.g. by creating appropriate
symlinks.

Addresses query in GitHub #406.

7e2af17783 repmgrd: tweak log notices when marking a standby as failed 
Announce what we're going to do (set the node record inactive) *before*
performing the action. Makes reading the log slightly easier.

e454fb77d3 While reviewing 7cb6e5af8d before merging 
I noticed that besides the result cleanup added, there was still a missing
spot inside the if condition.

Adding the PQclear that was missing.

b2eb9b8525 Correctly handle error message pointer when parsing strings. 
When parsing conninfo strings, ensure the error message pointer is
actually returned to the caller.

Not a criticial issue, just meant the contents of the error message
were not being displayed.

6fbbe2a97a "standby clone": fix --superuser handling 
get_superuser_connection() was erroneously using the local node record
to connect to as a superuser, which works when registering the primary
but obviously not when cloning a standby.

60e63feaca repmgrd: add configuration file parameter "standby_reconnect_timeout" 
This is used for determining a timeout when reconnecting to the standby
after executing the "follow_command". This will normally not need to be
set explicitly, but maybe useful in cases where the standby's startup
phase can last longer than usual.
