It seems reasonably unlikely that we'd change it. Even if we did,
we have in the past provided compatibility views (cf pg_user,
pg_shadow) when removing a catalog --- I would think the same would
happen for pg_database if we ever removed it.

The point of information_schema is that it's standardized. There
is no view in the SQL standard that corresponds to a list of databases.
If you think there ought to be, take it up with the SQL committee.
