Tables meet this naming spec. Columns, functions, operators, operator
classes/families, collations, constraints, and conversions do not (you
need more data to name them). Schemas, databases, languages, extensions,
and some other things also do not, because you need *less* data to name
them. Types also don't really meet this naming spec, because you need to
contend with special cases like "int[]" or "timestamp with time zone".
So this proposal doesn't seem very carefully thought-through to me,
or at least the use case is much narrower than it could be.
Also, if "object does not exist" isn't supposed to be an error case,
what of "name is not correctly formatted"? It seems a bit arbitrary
to me to throw an error in one case but not the other.
