Tablespace symlinks

Hi,
I'm using PostgreSQL 9.5.
As backup I use pg_basebackup with options *--format=t -v -z -P *.
These are the steps I do for restore:
1.
tar -xzf base.tar.gz -C $PGDATA
2.
for f in `ls | grep -v base.tar.gz `; do
echo "tar -xf $f -C $PGDATA/pg_tblspc/`echo $f|cut -d'.' -f 1`"
tar -xf $f -C $PGDATA/pg_tblspc/`echo $f|cut -d'.' -f 1`
done

I​ ha

​ problem because ​symlinks for my tablespaces are not being created in
step 1.

​According to
https://www.postgresql.org/docs/9.5/static/app-pgbasebackup.html :
"*When tar format mode is used, it is the user's responsibility to unpack
each tar file before starting the PostgreSQL server. If there are
additional tablespaces, the tar files for them need to be unpacked in the
correct locations. In this case the symbolic links for those tablespaces
will be created by the server according to the contents of
the tablespace_map file that is included in the base.tar** file.*"
my understanding is that these symbolic links should be created with the
first step.

I was using same approach with PostgreSQL 9.4, and it was OK.

So, is this new behavior in 9.5 (so I shall handle it manually), or I am
missing something?
