Hm. I think we'd have to switch around the order of stuff so that we
look at the flat-file copy of pg_shadow first. Then we'd know which
flavor of name we have, and we can proceed with the pg_hba match.
The reason it's worth doing this is that 'postgres', for example, should
be an installation-wide username even when you're using db-local names
for ordinary users.

What? We've been discussing raising NAMEDATALEN for months, and no
one's claimed that it qualifies as a protocol version change.
