mkdirs.sh contains incorrect path if $PGDATA and pg_wal are symbolic links

mkdirs.sh contains incorrect path if $PGDATA and pg_wal are symbolic links.

The situation is as follows.
OS : Red Hat Enterprise Linux release 9.3 (Plow)
Package : postgresql16-server
Architecture : x86_64
Version : 16.2-1PGDG.rhel9
pg_rman : pg_rman-1.3.16-1.pg16.rhel9.x86_64.rpm

PGDATA=/var/lib/pgsql/16/data

$ ls -l $PGDATA
lrwxrwxrwx. 1 postgres postgres 26 Mar 21 22:02 data -> /pgsql-data/dbcluster/data
$ ls -l $PGDATA/pg_wal
lrwxrwxrwx. 1 postgres postgres 31 Mar 25 00:05 pg_wal -> /pgsql-backup/online-wal/pg_wal

mkdir -m 700 -p /pgsql-data/dbcluster/data/pg_xact

rm -f ata/pg_wal
ln -s /pgsql-backup/online-wal/pg_wal ata/pg_wal

======================================
[correct path]
rm -f /var/lib/pgsql/16/data/pg_wal
ln -s /pgsql-backup/online-wal/pg_wal /var/lib/pgsql/16/data/pg_wal

Hi, Thank you for your issue.
pg_rman is not supput when $PGDATA is symbolic link.
but wher pg_wal is symbolic link pg_rman can do backup and restore.
