Decrypt for postgresql's native encrypt function?

[Cifer-Y]

Now I have a legacy database, a column is encrypted by PGP_SYM_ENCRYPT.

I wonder if I can use cloak_ecto to deal with that?

I'm not familiar with Postges's native encryption. It may be possible to develop a custom cipher module that is capable of decrypting the ciphertext though. See the docs on Cloak.Cipher: https://hexdocs.pm/cloak/Cloak.Cipher.html
