Thank you Luca,
For now I have seen the below:
pgp_pub_encrypt -- using public gpg key
pgp_pub_decrypt -- using secret gpg key
Select crypt('test', gen_salt('md5'));
Select PGP_SYM_DECRYPT(PGP_SYM_ENCRYPT('Some data','Secret password','compress-algo=1, cipher-algo=aes256'),'Secret password');
My question is, can I use the gpg public/secret key instead of the 'Secret password' in above PGP_Sym_encrypt/decrypt? I can create a wrapper function to read the public/secret keys to hide it from appearing as clear text.
still researching how to encrypt a column with sensitive data as a best practice to use in OLTP production with minimal impact on performance.
Regards

It is not clear what you are going to do and which kind of encryption
you are going to use.
For a symmetric encryption this could be a starting point:
UPDATE secret
SET secret_text = pgp_sym_encrypt( clear_text,
'A-Strong-Secret-Password' );
I do remember there was an extension made to overtake pgcrypto, but
currently I don't remember the name.
