RE: PostGreSQL TDE encryption patch

Hi

CYBERTEC provided good installation guide (https://www.cybertec-postgresql.com/en/products/postgresql-transparent-data-encryption/)

Here is their answer to your question :
Q: Can I upgrade to an encrypted database?
A: In place encryption of existing clusters is currently not supported. A dump and reload to an encrypted instance is required, or logical replication can be used to perform the migration online.

Subject: PostGreSQL TDE encryption patch

Hi,

We are migrating our product to PostGreSQL from Oracle and as part of HIPPA(https://en.wikipedia.org/wiki/Health_Insurance_Portability_and_Accountability_Act) guidelines, we have a requirement to encrypt entire tablespace/specific tables using Transparent data encryption(TDE).

I was looking at TDE solution in PostGreSQL and went through following wiki:
https://wiki.postgresql.org/wiki/Transparent_Data_Encryption

I found following TDE patch from this wiki:
https://www.postgresql.org/message-id/CAD21AoBjrbxvaMpTApX1cEsO%3D8N%3Dnc2xVZPB0d9e-VjJ%3DYaRnw%40mail.gmail.com

However, I am not sure how to apply this patch and I had the following questions:
1. We are using PostGreSQL 12. Is it possible to apply patches on top of existing PostGreSQL installation?
2. Will it be available anytime sooner with a major release like PostGreSQL 13?

Regards,
Chirag.
