Is a new, fixed version going to be posted soon?  It's been a while. 






Also, apologies if this has been asked before, but: how does this patch 

relate to the stuff being discussed in 

https://postgr.es/m/031401d3f41d$5c70ed90$1552c8b0$@lab.ntt.co.jp ? 








Hi Álvaro,



Thank you for a reply.


I mainly said that the issues in the src/backend/storage/file/encryption.c. If 
somebody want to use these patches, I think Antonin need to fix it.

It does not relate to the stuff being discussed in TDE. As I know, some company 
use these patches to encrypt data, even if these issues don't matter.



Regards,
