Re: [GENERAL] How to restore the table space tar files created by pg_basebackup?
Hi Venkat, I verified that the tablespaces are located in actual directories and not any symbolic links. Another interesting thing is that the content in these additional tar.gz files is already present in the base.tar.gz file.

It will be that if you have the tablespaces in the actual directories. The question is how and why you ended up with the tablespaces in the actual directories there, and not symlinks. It seems rather pointless to have tablespaces if they go in there... //Magnus On Thu, Dec 1, 2011 at 13:35, Samba saas...@gmail.com wrote: Hi Venkat, I verified that the tablespaces are located in actual directories and not any symbolic links.

Do you have Tablespace directories with a softlink to the data directory ?
