e53162deb8 Fix master port check
Check introduced in dc0dfe9b56

6a8336b880 Add "--checksum" in rsync when using "--force"
If the user don't put that option in rsync_options using of "--force"
could be unsafe.
While the probability of failures because of this are low they aren't
zero.

07a216ca25 If the user doesn't pass the port on which the primary server is listening
we have to assume it's the DEFAULT_MASTER_PORT.

This was not done, so we added a check to see if it has a value that is
usable, else we use DEFAULT_MASTER_PORT.

1aa36ca1c1 Properly specify rsync --exclude directories
Using '--exclude=dirname/*' to explicitly specify directories whose contents
should not be copied. This will result in empty directories being created
on the destination if they exist on the source, but that's not a problem as
they are needed anyway.

Previously the generated rsync command contained '--exclude=pg_log*', which
will break replication on 9.5 as the wildcard expansion prevents the
'pg_logical' directory from being copied.

04c101c5f0 rather big refactoring: use a naming scheme
In the past naming of functions, variables and such didn't really have a
