This can be used so that repmgr standby clone adds the string
specified in repmgr.conf as a restore_command in recovery.conf.
We can use this option for integration with barman by setting the
parameter to an appropriate get-wal call.
all the WALs needed without needing to set wal_keep_segments to
a ridiculously high value.
This is not necessary on 9.6 if we are using replication slots,
as all WAL segments needed will be kept on the primary until
they are consumed by the slot.
from the postgresql code so we use that instead of issuing system calls
with rm -rf ....
I also eliminated the rm -rf for pg_xlog.
Will later do the same with the other system call to remove files
in pg_replslot/
issue with rsync returning non-zero status on vanishing files on commit
83e5f98171.
Alvaro Herrera gave me some tips which pointed me in the correct
direction.

Although the witness server will resync the repl_nodes table following
a failover, other operations (e.g. removing or cloning a standby)
were previously not reflected in the witness server's copy of this
table.
As a short-term workaround, automatically resync the table at regular
intervals (defined by the configuration file parameter
"witness_repl_nodes_sync_interval_secs", default 30 seconds).
This fixes a bug introduced into the previous commit, where the
witness node was registered last to prevent a spurious node record
being created even if witness server creation failed.
Ensure witness is only registered after all steps for creation
have been successfully completed.
Also write an event record if connection could not be made to
the witness server after initial creation.
This addresses GitHub issue #146.
99.9% of the time they'll be the same as the primary connection, but
it's more consistent to use the provided local conninfo string
(from which the port is already extracted).
Optionally prompt for superuser and repmgr user when creating a witness.
This ensures a password can be provided if the primary's pg_hba.conf
mandates it.
This deprecates '--initdb-no-pwprompt'; and changes the default behaviour of
"repmgr create witness", which previously required a superuser password
unless '--initdb-no-pwprompt' was supplied.
This behaviour is more consistent with other PostgreSQL utilities such
as createuser.
Partial fix for GitHub issue #145.
Make the code match the documentation.
As pointed out by GitHub user phyber (#142).
Also various other minor improvements to error reporting during
config file parsing.
