I am looking to store all of my tables in PostgreSQL as aes 256 encrypted (due to client requirements). I will look at decrypting few columns for my analysis later. But apparently the encryption process is a drag as I have loads of tables. I am using update statements to pgp_sym_encrypt each column individually.
Is there a way to update the entire table easily or is there a better process instead of writing manual column update queries in each table??
Many thanks
