Actually, this does exist for some things in the catalog; I suspect it
just wasn't done in the past (perhaps Postgres didn't originally have
comments). I think it would be a useful addition. But I think it'd need
to be more than just a .sql file (initdb would probably need to be
modified). Ideally, we'd be able to suck the info out of the appropriate
.sgml files.
