I've just made these changes, and will commit them once I put in some
warnings about NULL usernames - my guess is that this should not stop
pg_dump, just warn the user.
It's a real pity about pg_get_userbyid - the output for non-existant users
is pretty near useless. I presume it's there for convenience of a specific
piece of code.
Would you see any value in creating a pg_get_usernamebyid() or similar that
returns NULL when there is no match?
