That is quite complicated to explain in plain English, so some sort of
pseudo-code is probably a good idea. I would recommend not to formulate
it as a SQL expression, though. It makes you think you could execute it
from psql or something. Even if you know that's not how to do it, it
feels confusing. Maybe something like:

<literal>md5</literal> hex_encode(md5(hex_encode(md5(password username)
salt)

with some extra markup to make it look pretty.
