Avoid including tablespaces inside PGDATA twice in base backups
Avoid including tablespaces inside PGDATA twice in base backups

If a tablespace was crated inside PGDATA it was backed up both as part
of the PGDATA backup and as the backup of the tablespace. Avoid this
by skipping any directory inside PGDATA that contains one of the active
tablespaces.
