This format causes the function to execute too many times:

AND card_number_enc != cc_encrypt('4111111111111111', 'pwd');
If the function is marked immutable that query should certainly evaluate
it only twice.
I notice that the EXPLAINs show it as credit_card_encrypt() not
cc_encrypt() --- maybe you got confused about which function you
were adjusting the properties of?
Sorry I was trying to shorten the function name to help with email
wrapping. It was credit_card_encrypt. I didn't do reps in all places.
So, that not being the problem, any ideas? Is it an 8.2.4 thing?
