The syntax we have used for the user/role case is ALTER USER
CURRENT_USER, not ALTER CURRENT USER, so this should be done in the same
way for databases.  Eventually, we'll also want ALTER DATABASE
current_database, and probably not ALTER CURRENT DATABASE, etc.

It's also curious that we don't support COMMENT on whatever CURRENT_USER
yet.  It looks like the previous patch to allow ALTER USER CURRENT_USER
etc. was not even applied to pg_dump.

I think this patch is a good direction to move in, and it seems everyone
else agreed, but I'm looking for a bit more of a holistic solution than
one command at a time here and there.  Define a goal such as, allow
restoring into a differently-named database, and then see what needs to
happen to achieve that.

The implementation looks generally OK, but I'm not sure why you need
this part:
