Thanks, that helped. This is what we did:
(to encode VARCHAR -> BYTEA)
update webuser set ccnum = decode(ccnumstring, 'escape') where userid=userid
(to decode BYTEA -> VARCHAR)
select encode(ccnum, 'escape') from webuser
But what about decrypting with the AES encryption algorithm?

Does
update webuser set ccnum = decode(ccnumstring::text, 'encode')
work?
