Indeed. We used to have a similar situation with respect to column
default expressions and CHECK constraint expressions. Eventually we got
rid of the textual storage of both, because it couldn't be maintained
in a reasonable way.
I think the answer here is "don't use the new syntax if you want the
function body stored textually". You can have one set of benefits,
or the other set, but not both at once.
